Informal Structures

B1 · IntermediateSpoken English Grammar

I think you're right. I'm gonna call you. And then we left. — the relaxed grammar of everyday speech.

What you'll learn

  • 'That' is often dropped after verbs like think, believe, say, hope when it introduces a clause: I think (that) you're right
  • Common reduced spoken forms: gonna (going to), wanna (want to), gotta (got to), hafta (have to), dunno (don't know), kinda (kind of)
  • Starting a sentence with 'and,' 'but,' or 'so' is completely natural in speech and increasingly accepted in less formal writing
  • The subject/auxiliary at the start of a question is often dropped in fast casual speech: (Are) You okay?
  • None of these are 'incorrect' — they're markers of an informal register, and should be avoided in formal writing and professional communication

The relaxed grammar of speech

Casual spoken English has its own set of everyday shortcuts that differ from careful written English — not because they're 'wrong,' but because speech favors speed and economy over formal precision. Recognizing these lets you understand native speakers easily and sound natural yourself in relaxed conversation, while knowing exactly when to switch back to full forms.

"I think you're right. (that dropped)"
"I'm gonna call you later. (going to reduced)"

Dropping 'that'

After verbs like think, believe, hope, say, and know, 'that' introducing the following clause is very often dropped in speech — the sentence is just as clear without it.

"I think (that) you're right."
"She said (that) she'd call."
"I hope (that) it works out."

Reduced spoken forms

A small set of very common verb phrases get pronounced — and often written casually, like in texting — as a single reduced word: gonna, wanna, gotta, hafta, dunno, kinda, sorta.

"I'm gonna call you later. (going to)"
"Do you wanna come? (want to)"
"I gotta go. (got to / must)"
"I dunno. (don't know)"

Starting with 'and,' 'but,' or 'so'

Despite an old classroom rule against it, starting a sentence with a conjunction is completely standard in speech, and common in informal or narrative writing. It's simply avoided in very formal registers.

"And then we just left."
"But I still think we should go."
"So what happened next?"

Watch out

✗I wanna apply for this position. (in a formal job application)
✓I would like to apply for this position.

Reduced spoken forms like 'wanna' and 'gonna' are fine in speech and texting, but they read as unprofessional in formal writing like emails, applications, or reports.

✗Dropping 'that' or starting a sentence with 'and' is a grammar mistake.
✓Both are completely standard features of natural spoken English — they're informal, not incorrect.

Don't confuse 'informal' with 'ungrammatical' — these structures are simply suited to a relaxed register, not errors to eliminate everywhere.

Real life — Texting a friend vs. writing to a professor

"gonna be late, stuck in traffic!"

"no worries, see you when you get here"

(later, in an email) "Dear Professor Lee, I am writing to let you know that I will be a few minutes late to class due to traffic."

"Good call switching it up for the email — that would've looked pretty casual for a professor."
