not jet (yet)

Quick answer

Use "not yet" - not "not jet." "Not yet" signals that something remains unfinished or hasn't happened up to now. "Not jet" is a phonetic typo, not standard English.

Wrong: I have not jet finished my homework.
Right: I have not yet finished my homework. / I haven't finished my homework yet.

Core explanation

"Yet" appears in negative sentences and questions to indicate that an action is expected but hasn't occurred so far. It commonly follows the auxiliary verb (have, do, be) or comes at the end of the clause.

With perfect tenses: I have not yet replied. / I haven't replied yet.
With auxiliaries: She is not yet ready. / Are they ready yet?
Placement affects emphasis: "I have not yet" gives a slightly more formal or emphatic tone than "I haven't yet."

The error "not jet" happens because the spoken /ɛt/ sound can be misheard or mistyped as "jet." Treat it as a common typo to fix during proofreading.

Grammar notes: spacing and hyphenation

"Not yet" is two separate words. Never hyphenate or fuse them. Keep the standard spacing and follow normal verb-auxiliary order.

Correct: They have not yet decided.
Also correct: They haven't decided yet.
Incorrect: They have not-yet decided. / They have notyet decided.

How to fix your own sentence (rewrite help)

Fixing "not jet" often means replacing it with "not yet" or rearranging the sentence for natural flow. Read the whole sentence after the change to check tone and clarity.

Step 1: Identify the auxiliary verb and the main verb (have + past participle, is + adjective, etc.).
Step 2: Replace "jet" with "yet" and place it where native usage prefers (after the auxiliary or at the end).
Step 3: Reread and, if needed, convert to a contraction for a conversational tone (haven't/hasn't).

Three rewrite examples:

Original: This plan is not jet workable for the deadline.
Rewrite: This plan is not yet workable for the deadline.
Original: The assignment feels not jet complete.
Rewrite: The assignment is not yet complete.
Original: Is that not jet possible this afternoon?
Rewrite: Isn't that possible yet this afternoon? / Is that not yet possible this afternoon?

A simple memory trick

Link the word "yet" to the idea of "up to now." When you mean "so far, but not now," picture "yet" at the edge of the action. That mental image discourages the "jet" typo.

Think: "not yet = still not done."
When proofreading, scan for the sequence "not j" - it's often a telltale sign of the typo.
Search your drafts for "jet" next to auxiliaries (have/is/has) and correct in bulk.

Similar mistakes to watch for

Spotting one spacing or phonetic typo makes it easier to catch related problems. Watch for these patterns:

Other phonetic typos (their/there/they're, your/you're).
Hyphen misuse (well known vs. well-known where applicable).
Incorrect auxiliary placement (have not + past participle vs. have + not + past participle for emphasis).
Contractions omitted when they would read more naturally (I have not → I haven't).

FAQ

Is "not jet" ever correct?

No. "Not jet" is a typo. Use "not yet" in standard written English.

Where should I put "yet" in a sentence?

After the auxiliary verb (have/has/is) or at the end of the clause. Both positions are correct; the choice changes emphasis slightly.

Can I use contractions?

Yes. Contractions like "haven't" or "isn't" are natural in informal writing and speech.

How do I choose between "not yet" and "yet" at the end?

Both work. "I haven't finished yet" is common and conversational. "I have not yet finished" is clearer or more formal.

Will spellcheck catch "not jet"?

Sometimes, but not always-especially if "jet" is a valid word in other contexts. Manual proofreading focusing on auxiliary + verb combinations is safest.

Check the whole sentence before you send it

Always read the sentence in context. Replacing "jet" with "yet" fixes the typo, but confirming the tense, tone, and flow ensures your message reads naturally.
