🎩 Lesson 7.1: Register — Formal vs Informal English

What Register Is

Register is not about "good English" versus "bad English." All of it is good English — the point is that language exists on a scale, from very informal to very formal, and a confident speaker slides up and down that scale to fit the moment. Think of it as a dial, not a switch:

    A["Very informal
text a friend"] --> B["Neutral
talk to a colleague"]
    B --> C["Very formal
write to an official"]
                

The same idea can be dressed three ways:

Notice that none of them is wrong. The formal one to a friend would sound cold and strange; the informal one to a company you're complaining to would undercut you. Register is about fit.

The Four Features That Shift

When English moves from informal to formal, four things change in a predictable way. Learn these four and you can consciously "turn the dial" in either direction.

1. Word choice

Formal English tends to prefer single, often Latin-based verbs where informal English uses everyday words and phrasal verbs. The meaning is the same; the flavor is not.

2. Contractions

Informal English is full of contractions — I'm, don't, we'll, it's, can't. Formal writing avoids them and spells the words out in full.

3. Sentence length and complexity

Informal English uses short, punchy sentences and lots of and / but / so. Formal English builds longer, more complex sentences with linking words, and states things more completely.

4. Set phrases

Certain fixed openings, closings, and requests instantly signal the register. Swapping these is often the fastest way to shift a whole message.

Spoken Register: Same Situation, Two Voices

Register isn't only about writing. In speech we shift too — a casual, direct voice with friends, and a more polite, tentative voice with strangers or people in authority. Polite spoken English softens requests with modals (could, would), hedges (I was wondering, would it be possible), and fuller sentences. Here is the very same situation — asking to change a reservation — handled two ways.

Before you move on, check your understanding of the two exchanges:

Written Register: The Formal Email

The place register matters most for a B2 learner is the formal email or letter — a complaint, an inquiry, a request. These follow a clear five-part structure. Once you know the skeleton, you only change the details.

Here is the whole thing assembled — a short letter of complaint:

A useful test: read your formal email and ask, "Could I say this to a stranger in a suit without cringing?" If any line sounds like something you'd only say to a close friend — "Anyway, get back to me!" — reach for the formal set phrase instead: "I look forward to your reply."

Your Phrase Bank

Keep these formal/informal pairs where you can reach them. When you need to shift register fast, swapping the set phrase does most of the work.

Tips & Common Mistakes

✅ Do's

• Read the situation first. Ask who your reader is and how well you know them, then choose the register to fit.
• Spell contractions out in full in formal writing — do not, I am, will not.
• Lead with your purpose in a formal email: "I am writing to…" in the very first line.
• Close formally — Sincerely, works after any formal greeting. (British English: named person → Yours sincerely; no name → Yours faithfully.)
