7.3 Modality, Font & Craft Features That Signal Purpose
Key Takeaways
- Modality (must, might, certainly, possibly, should, could) is a writer's craft choice that signals degrees of certainty, obligation, or possibility—not only a grammar label.
- High modality sounds definite and forceful; low modality sounds cautious, tentative, or polite—each suits different purposes and audiences.
- Italics, bold, CAPITALS, and other type treatments can mark scientific terms, titles, emphasis, or shouting; on ICAS they are craft signals when the extract shows them.
- Tense and typeface/register choices help reveal purpose (instruct, persuade, recount, hypothesise) and intended audience.
- Always link the craft feature back to purpose and audience: what does this certainty level or emphasis make the reader think or do?
7.3 Modality, Font & Craft Features That Signal Purpose
Some craft tools are flashy (a blazing metaphor, a billboard slogan). Others are quiet dials the writer turns: how certain a claim sounds, which words are emphasised in type, and which tense carries the action. The ICAS English writer's-craft strand treats these as meaning-makers. This section trains you to read modality, font/type emphasis, and related craft features as signals of purpose and audience.
Quick Answer: Modality = language of certainty, possibility, and obligation (must, might, certainly, possibly, should). Type emphasis (italics, bold, capitals) highlights special terms or force. Together with tense and register, these choices show how strongly a writer wants you to believe, obey, or keep an open mind.
Modality as a craft choice
In syntax chapters you may meet modality as a grammar topic (modal verbs). Here the angle is craft: the writer chooses a certainty level to shape the reader's trust and response.
A simple scale
| Strength | Example language | Reader effect |
|---|---|---|
| Very high | must, have to, will (as certainty), certainly, definitely, always, never | Sounds absolute; little room to disagree |
| High | should, need to, clearly, undoubtedly | Strong guidance or confident claim |
| Medium | can, tend to, often, likely, probably | Balanced; allows exceptions |
| Low | might, may, could, possibly, perhaps, seems | Tentative; cautious or polite |
| Lowest / open | might not, one possibility is, it is unclear whether | Invites doubt or further inquiry |
Same content, different modality:
- High: Students must wear helmets on the cycle track.
- Medium: Students should wear helmets on the cycle track.
- Low: Students might want to wear helmets on the cycle track.
Craft reading:
- Sentence 1 → rule / safety regulation voice; purpose often to compel.
- Sentence 2 → advice / policy recommendation; firm but slightly softer.
- Sentence 3 → optional suggestion; weak for a safety campaign, fine for a casual tip.
Purpose and audience decide which dial setting is appropriate. A scientific discussion section often prefers medium/low modality (results suggest, may indicate) to avoid overclaiming. A protest placard prefers high modality (We will not accept…).
Modality beyond modal verbs
Modality is not only must/might. Watch for:
| Device | Examples | Certainty colour |
|---|---|---|
| Modal verbs | must, shall, may, could | Core scale |
| Modal adverbs | certainly, possibly, arguably | Boost or soften |
| Adjectives | certain, likely, potential, inevitable | Frame claims |
| Phrases | it is clear that, there is a chance that | Explicit stance |
| Frequency words | always, never, sometimes, rarely | Absolute vs partial |
| Hedging | appears to, tends to, to some extent | Scientific caution |
Original pair — council notice vs science fair abstract
Notice (high modality):
Path users must keep dogs on leads. Fines will apply.
Purpose: regulate behaviour. Audience: all park users. Craft: high obligation + future certainty of enforcement.
Abstract (low–medium modality):
Filtered light may improve germination rates. Further trials are needed before farm-scale claims can be made.
Purpose: report provisional findings. Audience: judges/teachers who value caution. Craft: hedges protect credibility.
On ICAS, a stem might ask what the writer's use of may suggests—often uncertainty, scientific caution, or politeness, depending on context.
Linking modality to purpose and audience
| Purpose | Typical modality | Why |
|---|---|---|
| Command / safety rule | High (must, do not) | Removes wiggle room |
| Persuade gently | Medium–high (should, need to) | Pressure without full threat |
| Sell with hype | High on benefits (will transform) | Confidence sells—watch exaggeration |
| Inform scientifically | Low–medium hedges | Accuracy over drama |
| Speculate / predict | Low–medium (might, could) | Future is not locked |
| Be polite to power | Low–medium (could we consider) | Softens request to authority |
Audience shift example (original):
- To children: You must wash your hands before lunch.
- To adult staff: Staff should ensure handwashing stations are stocked.
- To researchers: Compliance rates might rise if signage is redesigned.
Same hygiene topic; modality and address change with audience and purpose.
Italics, font, and type as craft signals
Printed exam extracts sometimes show italics, bold, or other emphasis. Treat them as deliberate.
Common jobs for italics
| Use | Example | Effect / signal |
|---|---|---|
| Scientific or technical term on first use | The chrysalis hardens overnight. | Marks specialist vocabulary; educates gently |
| Title of a work | She quoted The Hidden Tide. | Convention of titling; literary/academic register |
| Emphasis | He was the only witness. | Stresses contrast or exclusivity |
| Word as word | The word yield has two meanings here. | Metalinguistic focus (language about language) |
| Character thought (some fiction styles) | Not now, she thought. | Interior voice |
| Foreign word | They ordered gelato. | Marks non-English item |
Bold often flags UI labels, warnings, or subheads in informational texts. ALL CAPS can signal shouting, acronyms, or poster emphasis—tone may become aggressive or urgent.
Original webpage-style line:
Tap Start Trial only if you accept the automatic renewal clause.
- Start Trial → interface label (procedural clarity).
- automatic renewal → emphasis on a term the writer wants noticed (consumer caution).
Craft question angle: Why italicise automatic renewal? → to highlight a condition readers might miss; supports a protective or critical purpose toward the offer.
When font/type signals purpose
| Type choice | Possible purpose signal |
|---|---|
| Heavy bold warnings | Safety, compliance, urgency |
| Italics for species/scientific names | Scientific or educational register (Homo sapiens style conventions in advanced texts) |
| Playful mixed caps in a title | Informal entertainment branding |
| Monospace or "code-like" styling in a digital extract | Technical, computing context |
| Sparse plain type, no emphasis | Neutral report; authority through calm |
You will not always see fancy fonts in a paper booklet. When the extract does mark emphasis, the exam almost always considers it fair game for a craft or comprehension stem.
Tense as a craft and purpose signal
Tense is grammar—and craft.
| Tense pattern | Common purposes |
|---|---|
| Simple past recount | Diary, news story of a finished event, narrative |
| Present simple | Facts, blurbs, live commentary, timeless claims, stage directions |
| Present continuous | Ongoing action, live blog feel |
| Future (will / going to) | Promises, predictions, threats, plans, calls to action |
| Present perfect | Linking past events to now (has risen, have failed)—often persuasive or analytical |
Original contrasts:
- The committee banned phones. → completed policy event (report).
- The committee bans phones. → sounds like a standing rule (regulation voice).
- The committee will ban phones. → announcement/promise; future pressure.
- The committee has banned phones three times and reversed twice. → pattern used to argue unreliability.
When purpose is to show a trend that still matters, present perfect is a craft ally. When purpose is to narrate a story world, past tense dominates.
Putting the signals together
Writers stack modality, type emphasis, and tense.
Original extract A — campaign email
We must act before Friday. The wetlands will not recover if the bulldozers arrive. Sign now.
| Feature | Reading |
|---|---|
| must | High obligation |
| Bold (if shown) / stressed urgency | Visual push |
| will not | High-certainty negative future |
| Imperative Sign now | Call to action |
| Inclusive We | Solidarity |
Purpose: persuade immediate action. Audience: already sympathetic list subscribers.
Original extract B — methods paragraph
Samples were dried for 24 hours. Mass was recorded to the nearest 0.1 g. Results should be interpreted cautiously because humidity may have varied overnight.
| Feature | Reading |
|---|---|
| Past passive | Impersonal scientific method |
| should + may | Medium/low modality hedges |
| Precise units | Technical audience |
Purpose: inform with credibility. Audience: teachers/assessors of a report.
If you swapped Extract A's modality into Extract B (Humidity must have ruined everything!), the scientific purpose would collapse into drama.
Framework writer's-craft strand: why this section exists
Across ICAS English papers, writer's craft is not only figurative language. Students are expected to notice how choices create effects—including how certain a writer sounds and how presentation features guide reading. Modality, emphasis, and tense are portable tools: they appear in literary narration (she might have imagined the footsteps), in factual writing, and in persuasion. Training them here bridges craft (this chapter) and syntax/modality work later in the guide, without treating them as empty labels.
Common traps
- Grammar-only trap: Defining might as "modal verb" without stating the effect (softens the claim).
- Always = wrong trap: High modality is not "bad"; it is wrong only when the purpose needed caution—or when an option overstates what the word does.
- Ignoring italics: Skipping type cues the setter deliberately included.
- Tense blindness: Missing that a shift to future tense turns information into a threat or promise.
- Audience amnesia: The same must addresses a child differently than a minister; use context.
A 35-second method for modality/type items
- Box the modal word or emphasised term.
- Place it on the certainty scale (high / medium / low).
- Name purpose of the whole text in a few words.
- Ask whether the certainty level matches that purpose (compel, caution, predict, sell).
- Choose the option that links feature → effect → purpose; reject options that only restate the plot.
Quick drill (say the effect aloud)
- certainly vs possibly
- must not vs should not
- will vs might
- italics on a scientific term vs italics for stress
- past recount vs future promise
If you can state each effect in one sentence, you are ready for craft items that never mention the word "modality" but still test it.
Modality, font emphasis, and tense complete this chapter's map of persuasion and conventions: not only what devices appear, but how strongly and how visibly a text steers its reader. Together with rhetorical techniques and text-type layout, they equip you to answer writer's-craft questions with evidence, precision, and purpose-awareness—the combination ICAS English rewards.
A lab report states, "The copper solution may contain traces of iron." What does the writer's choice of may most clearly signal as a craft decision?
In an online safety notice, the phrase automatic renewal appears in italics in the sentence "Check the box only if you agree to automatic renewal." What is the most likely craft reason for the italics?
