The Degree Ladder

• Downgraders (below full strength) → slightly · somewhat · fairly · rather · quite
• Upgraders (at or above) → pretty · really · very · extremely · incredibly
• Maximisers (for absolutes only) → absolutely · completely · utterly

• slightly — ~10% · neutral, precise · "slightly slower"
• a bit / a little — ~15% · casual · "a bit tired"
• somewhat — ~30% · formal, written · "somewhat unusual"
• fairly — ~50% · neutral · "fairly fast"
• rather — ~55% · British, often disapproving · "rather expensive"
• quite — ⚠️ 50% or 90% · dialect-dependent · "quite good"
• pretty — ~70% · informal, very common · "pretty good"
• really — ~85% · neutral, all-purpose · "really good"
• very — ~85% · neutral, slightly flat · "very good"
• extremely — ~95% · formal, strong · "extremely rare"
• incredibly — ~95% · informal, emphatic · "incredibly slow"
• absolutely — 100% · for non-gradables only · "absolutely impossible"

The percentages are a teaching aid, not linguistics. Use them to feel the gaps, then forget them.

Slightly and extremely are safe — they mean what they look like. The danger zone is fairly / rather / quite, because these look neutral but carry downgrade and sometimes attitude.

"Your English is fairly good."

That is not a compliment. It's a B1 assessment. But it looks like praise to a learner, because it's positive-shaped.

The test: would the sentence be stronger with the adverb deleted? If yes, you're on a downgrade rung.

• "It's good." > "It's fairly good." ✅ (the adverb weakened it)
• "It's good." < "It's really good." ✅ (the adverb strengthened it)

Best rung for technical honesty. "Slightly slower, but far more readable" is a real trade-off statement.

A bit before a positive adjective sounds odd: ❌ "a bit brilliant". Downgraders naturally attach to negatives — a bit slow, a bit messy, a bit late.

In speech it sounds stiff. In a report it sounds considered.

Rather can modify verbs; fairly can't. "I rather enjoyed it" ✅ / ❌ "I fairly enjoyed it."

• 🇬🇧 "quite good" = fairly good. Lukewarm, faintly disappointing.
• 🇺🇸 "quite good" = very good. Genuine praise.

A British reviewer writing quite good is not praising you.

Avoid quite whenever the stakes matter. Say fairly for moderate, very for strong.

With non-gradable adjectives, quite means completely in both dialects: "quite impossible", "quite right", "quite finished", "quite different".

Informal. Fine in Slack and casual client email, weak in a proposal or contract.

In writing, a stronger adjective usually beats very + a weak one. Very fast → rapid. Very tired → exhausted. Very important → critical. This one substitution visibly raises your written English.

Use sparingly. If everything is extreme, nothing is.

Gradable adjectives have degrees: fast, good, tired, expensive, clear. They take slightly … extremely.

Non-gradable adjectives are already absolute: perfect, impossible, unique, essential, free, dead, finished, correct, identical. They take absolutely / completely / totally / quite, and refuse the ladder.

• ❌ "very perfect" → ✅ "absolutely perfect"
• ❌ "fairly impossible" → ✅ "completely impossible"
• ❌ "extremely unique" → ✅ "truly unique"
• ❌ "very finished" → ✅ "quite finished"

broken, deprecated, deterministic, idempotent are non-gradable. Something isn't "very deprecated" — it's deprecated or it isn't.

• slightly — ✅ · ✅ · ✅ (slightly prefer) · ❌
• somewhat — ✅ · ✅ · ⚠️ rare · ❌
• fairly — ✅ · ✅ · ❌ · ❌
• rather — ✅ · ✅ · ✅ · ⚠️ "rather a mess"
• quite — ✅ · ✅ · ✅ · ✅ "quite a change"
• pretty — ✅ · ✅ · ❌ · ❌
• really — ✅ · ✅ · ✅ · ❌
• very — ✅ · ✅ · ❌ · ❌
• extremely — ✅ · ✅ · ❌ · ❌

• ❌ "I very like it." → ✅ "I really like it."
• ❌ "I fairly agree." → ✅ "I quite agree." / "I rather agree."

Default: article first. Exceptions: quite, rather, such.

• "Slightly slower, but far more readable." (honest trade-off)
• "The docs are fairly good." (usable, not great)
• "That's a rather large function." (British criticism)
• "Pretty confident it's a caching issue."
• "Extremely unlikely to happen in production."
• "The two outputs are completely identical." (non-gradable)
• "This dependency is quite unnecessary." (= entirely, with a non-gradable)

• "It's a fairly small change on our side." (honest hedge on scope)
• "I'm pretty confident we'll hit Friday." (warm, informal)
• "That's extremely helpful, thank you." (strong, sincere)
• "The requirement is somewhat unclear — could you confirm?" (formal, non-accusatory)
• "Slightly over the original estimate; here's why."

Use downgraders for scope, risk and difficulty. Use upgraders for gratitude and enthusiasm. Never the reverse.

• ✅ "a fairly small change" + "extremely helpful, thanks"
• ❌ "a very small change" (overpromising) + "somewhat helpful, thanks" (cold)

• "A bit tired, but fine."
• "It's fairly close — fifteen minutes."
• "Rather cold for August."
• "Pretty good coffee, actually."
• "The flat's extremely quiet, which I didn't expect."

🎚️ A mixing desk, not a switch. Every fader has a labelled position, and the labels are not evenly spaced. Fairly sits at halfway even though it feels like three-quarters — that gap between where it feels and where it sits is the entire lesson.

Fairly · Basically / Essentially / Effectively · Roughly / Approximately. Not written yet: quite / pretty / rather.

Which is impossible?

• ✅ "a fairly simple fix"
• ✅ "quite a change"
• ❌ (impossible) "fairly a simple fix" — the article comes first. Quite and rather are the exceptions that precede it.

Which sentence is wrong?

• ✅ "I really like it."
• ❌ (wrong) "I very like it." — very cannot modify a verb.
• ✅ "I quite like it."

Which undersells you in a proposal?

• ❌ (undersells) "I'm somewhat experienced with RAG pipelines." — a middle rung reads as a literal self-assessment, not modesty.
• ✅ "I've built four RAG pipelines this year."
• ✅ "RAG pipelines are a core part of my work."

1. completely — identical is non-gradable; it takes a maximiser, not a degree word.
2. rather — the British idiom I rather like it. Fairly can't modify a verb at all.
3. extremely — unlikely is gradable, so it takes a degree adverb; the maximisers don't fit.
4. fairly good — a downgrade in British English, praise in American. Same words.
