Nuance in Formal vs Informal English

At advanced level, the distinction between formal and informal English goes beyond vocabulary. It involves subtle choices of grammar, syntax, hedging, and stance.

Stance and hedging (formal)

Hedged vs. unhedged

Informal: "This proves that the policy failed."

Formal: "This evidence suggests that the policy may have been less effective than anticipated."

Impersonal constructions

Personal vs. impersonal

Informal: "I think we should look at this more carefully."

Formal: "It would be advisable to examine this matter more thoroughly."

Formal: "Further examination of this issue is warranted."

Tip: The most common advanced register error is using informal vocabulary in a formal structure — or vice versa. Aim for internal consistency: every element of your sentence should belong to the same register.
