Lesson 9: Adjectives & Adverbs — Description, Degree & Author's Tone
Why 'extremely effective', 'relatively effective', and 'surprisingly effective' are three different claims, not three synonyms — and how degree, certainty, frequency, and hedging words reveal an author's actual confidence, not just their description.
Learning Objectives
By the end of this lesson, you should be able to:
- Tell an adjective (describes a noun) apart from an adverb (modifies a verb, adjective, another adverb, or a whole sentence)
- Read adverbs of degree (very, highly, relatively, extremely) as a strength signal, not just a word to translate
- Recognise adverbs of certainty (certainly, probably, possibly) as the author's stated confidence level
- Recognise hedging language (may, might, could, tends to, appears to) and understand why academic writers reach for it
- Find the head noun inside a noun phrase stacked with an adverb + adjective + noun modifier chain
Introduction
Today's topic makes a real difference to how precisely you read. An author rarely just writes:
The decision was good.
They might instead write:
The decision was extremely effective. The decision was relatively effective. The decision was surprisingly effective.
These are not three ways of saying the same thing. Adjectives and adverbs are not just grammar — they carry the author's judgment, certainty, emphasis, and tone.
What Is an Adjective?
An adjective gives information about a noun or pronoun — answering what kind? which one? how much? what quality?
a difficult problem · an effective strategy · an experienced manager · a complex situation
problem → difficult · strategy → effective · manager → experienced · situation → complex
Where Does an Adjective Sit?
Most commonly, directly before its noun:
an important decision · a successful company · a complex problem · useful information
But an adjective can also come after the noun, connected through a linking verb:
The problem is difficult. · The strategy is effective. · The situation became complex.
Adjectives After a Linking Verb
Some verbs connect a subject to its state, not to an action
Verbs like be, become, seem, appear, feel, look, remain, stay don't describe an action — they connect the subject to a description of its current state.
The problem is difficult. · The situation became complicated. · The idea seems reasonable. · The explanation appears convincing.
In each case, the adjective describes the subject's condition.
What Is an Adverb?
An adverb gives extra information about a verb, an adjective, another adverb, or even an entire sentence — answering how? to what degree? when? where? how certain? how often?
People carefully analyze information. — how do they analyze? carefully. She speaks slowly. — how does she speak? slowly.
Adjective vs. Adverb
Adjective describes a noun; adverb modifies an action or description
He is a careful researcher. — careful describes researcher (adjective).
He works carefully. — carefully describes how the work happens (adverb).
Many, Not All, Adverbs End in -ly
careful → carefully · quick → quickly · effective → effectively · clear → clearly · significant → significantly · gradual → gradually
Don't rely on the ending alone
fast, hard, well, often, very are all adverbs, none of them ending in -ly. Check the word's function in the sentence — what it's modifying — not its spelling.
Adverbs of Degree — "How Much?"
These matter enormously in non-fiction: very, extremely, highly, relatively, fairly, quite, somewhat, slightly, significantly, particularly.
Degree words change the strength of a claim
The problem is very difficult. — a high degree of difficulty.
The problem is extremely difficult. — even stronger.
The problem is slightly difficult. — a low degree.
A Rough Scale for Degree
slightly → somewhat → fairly → quite → very → extremely
This isn't a precise mathematical scale — context can shift each word's real strength — but it's a useful rough ordering to keep in mind.
VERY vs. EXTREMELY
The result is very important. — strong importance. The result is extremely important. — even stronger emphasis.
Academic writing often reaches for highly significant or particularly important to signal this same kind of emphasis.
HIGHLY
A very common formal intensifier: highly effective · highly important · highly successful · highly influential.
This is a highly effective method. — highly raises the degree of effective.
RELATIVELY
relatively means 'compared to something else', not 'absolutely'
relatively = compared to something else, not in an absolute sense.
The method is relatively simple. — not claiming the method is simple on its own terms; claiming it's simple compared to other methods.
The book is relatively easy to read. — easier than other, harder books — not necessarily easy in any absolute sense.
PARTICULARLY
particularly = especially, specifically for this case
This is particularly important for beginners. — not equally important for everyone; specifically emphasised for beginners.
SIGNIFICANTLY — Two Meanings
significantly can mean two different things
Meaning 1 — noticeably/considerably: Performance improved significantly. — a noticeable amount of improvement.
Meaning 2 — a marker of importance: Significantly, the researchers found no major difference. — here the author is signalling: this fact deserves your particular attention.
Adverbs of Certainty
These reveal how confident the author actually is: certainly, clearly, obviously, probably, possibly, perhaps, likely, unlikely, apparently.
Certainty words change the strength of a claim, not just its wording
This causes the problem. — a direct, strong claim.
This probably causes the problem. — the author shows some uncertainty.
This may cause the problem. — even more open to possibility.
A Rough Certainty Scale
certainly → probably → possibly
Certainty decreases as you move along this scale.
The same claim at three levels of confidence
Certainly: This is certainly important. — strong confidence. Probably: This is probably important. — likely, not certain. Possibly: This could possibly be important. — a real possibility, nothing more.
Modal + Adverb
A combination you'll meet constantly in real books: may possibly, will probably, can often, may significantly, could potentially.
Breaking down a modal + adverb + verb chain
Social environment can significantly influence behavior.
can → possibility/ability · significantly → degree · influence → main verb · behavior → object.
Adverbs of Frequency — "How Often?"
always → usually → often → sometimes → rarely → never
Position of Frequency Adverbs
Frequency adverbs usually sit before the main verb — but after 'be'
People often make mistakes. · Researchers usually examine the evidence. — before the main verb.
People are often influenced by emotions. — after be.
How an Adverb Reveals the Author's Tone
The same claim, four different levels of confidence
The theory is wrong. — flat, direct. The theory is probably wrong. — lower certainty. The theory is clearly wrong. — higher certainty. The theory is arguably wrong. — the author is saying: this is a defensible interpretation, but not necessarily the only one.
Each version makes a genuinely different claim about how confident the author is — this is some of the most valuable information in academic reading.
Hedging — A Cornerstone of Academic English
Academic writers often avoid absolute claims on purpose
Instead of stating something as flatly certain, writers often reach for: may, might, could, tends to, appears to, seems to, is likely to, possibly, probably.
Strong: Stress causes poor decisions.
Hedged: Stress may contribute to poor decisions.
More cautious still: Stress may be associated with poorer decision-making.
This softening of a claim's strength is called hedging.
Why Do Authors Hedge?
Because evidence rarely proves absolute certainty
Exercise improves mental health. — a broad, direct claim.
Exercise may improve mental health. — genuine uncertainty is acknowledged.
Exercise has been associated with better mental health. — describes a relationship the evidence shows, without claiming direct causation.
Recognising this pattern makes research papers and serious non-fiction dramatically easier to read accurately.
Adjective + Preposition, Revisited
Connecting back to Lesson 7:
interested in · responsible for · aware of · familiar with · similar to · different from · capable of · important for
Researchers are interested in human behavior. · People should be aware of their biases. · The two methods are similar to each other.
Stacking Adverb + Adjective + Noun
Reading a stacked modifier chain from the outside in
a highly effective communication strategy
strategy = head noun · communication = noun modifier · effective = adjective · highly = adverb modifying effective.
highly → effective → communication → strategy
Another Stacked Noun Phrase
Peeling back the layers
an extremely important psychological factor
factor = head noun · psychological = what type of factor · important = the factor's quality · extremely = the degree of important.
Core: factor.
Reading Strategy: Find the Head Noun First
Connecting back to Lesson 3: the technique is unchanged, but today's modifiers are degree and certainty words rather than plain description, so it's worth re-testing the habit here.
However many modifiers stack up, the head noun anchors the phrase
The highly influential ideas of several experienced researchers…
Head noun: ideas
Modifiers: highly influential (before) · of several experienced researchers (after).
Find the head noun first, then add the details back around it.
Guided Reading Practice
Read the paragraph once, slowly, and underline every word that signals degree, certainty, or frequency rather than plain description.
People are often influenced by factors that they do not consciously recognize. These influences can be particularly important when individuals are making complex decisions. However, people may not always be aware of how strongly their emotions affect their judgment. Researchers have therefore increasingly examined the unconscious processes that may contribute to decision-making. Although these processes can be difficult to measure directly, they may significantly influence human behavior.
Notice the author's language choices:
often — frequency: how often? particularly — emphasis: specifically important here. may not always — uncertainty combined with frequency. increasingly — a trend, growing over time. unconsciously — the opposite condition of awareness. directly — how something is measured. significantly — degree/emphasis.
The Paragraph's Hidden Meaning
Literal content vs. the author's actual stance
The literal content: people can be influenced by unconscious factors.
But the author's actual stance, carried entirely by the hedging words: these factors may influence behavior — the author is not claiming absolute certainty.
Missing this distinction means missing exactly how confident the writer actually is — which is often the whole point of a careful academic sentence.

Recognising these shapes instantly, as single units, is what fast, accurate reading is built from.
Golden Rule
Three questions for any adjective or adverb
Never jump straight to a Bangla translation. Answer these three questions first, and the word's real contribution to the sentence becomes clear. Everything you met today collapses into one small map:
ADJECTIVE → describes a noun/state
ADVERB → modifies action / description / degree / certainty / frequency
DEGREE → very / highly / extremely / relatively
CERTAINTY → certainly / probably / possibly / apparently
FREQUENCY → always / usually / often / rarely
HEDGING → may / might / could / tends to / appears to
Golden Rule
An adjective or adverb is never just decoration — it's the author telling you how certain, how strong, or how frequent something is. Read it for that signal, not only for its dictionary meaning.
Lesson Summary
Today you learned that an adjective describes a noun while an adverb modifies a verb, adjective, another adverb, or a whole sentence — and that neither is decoration. Degree words (very, highly, relatively, extremely) tell you how strong a claim is; certainty words (certainly, probably, possibly) tell you how confident the author actually is; and hedging language (may, might, tends to, appears to) is a deliberate academic habit for avoiding overstated claims. You also practised peeling back a stacked adverb + adjective + noun modifier chain to find the head noun underneath it.
Practice: Test What You've Learned
Work through every question yourself before checking anything.
Before you start
Do not use Google Translate or any other translation tool for these questions. Misjudging an author's certainty is a very normal mistake at this stage — it's exactly what this lesson exists to sharpen.
Part A — Identify the Function
- The researcher carefully examined the evidence. — what does carefully modify?
- This is a highly effective method. — what does highly modify?
- People often make decisions emotionally. — what does often express?
- The results are relatively consistent. — what does relatively express?
- The evidence may possibly support the theory. — what attitude does may possibly show?
Part B — Adjective or Adverb?
Say whether the bold word is an adjective or an adverb.
- an effective strategy
- work effectively
- a careful analysis
- analyze the data carefully
- a significant improvement
- performance improved significantly
Part C — Author's Certainty
Order these three sentences from strongest to weakest certainty.
- This is certainly the main cause.
- This may be the main cause.
- This is probably the main cause.
Part D — Reading
- Decode this sentence's structure: The highly effective strategy significantly improved the performance of inexperienced employees. Identify the head noun, the adjective, the adverb, the main verb, the object, and who is described as inexperienced.
Part E — Meaning
Explain the difference between these two sentences — not just their translation, but the strength of the claim each one makes.
- Stress causes poor decisions.
- Stress may contribute to poor decisions.
Part F — Advanced Reading
- Identify the author's certainty and tone in this paragraph: Recent research suggests that social interaction can significantly affect human behavior. However, the effects may vary considerably between individuals. People who regularly interact with supportive social networks may be more likely to develop positive behavioral patterns. Nevertheless, these relationships should not necessarily be interpreted as direct evidence of causation. Identify: which word shows the author's uncertainty, which word shows degree/emphasis, which word shows contrast, which phrase shows possibility, and why the final sentence is so cautious.
Next: Lesson 10 — Pronouns & Reference Tracking: he, they, it, this, that, these, those, which, who — quickly identifying exactly which person, idea, or object the author is talking about. This matters enormously for reading long English books, because the hardest part of a paragraph is often not its vocabulary, but figuring out exactly what "it", "they", "this", or "which" is actually referring to.
