all most (almost)

If you mean "nearly" or "not quite," write almost as one word. Writing "all most" is usually a spacing or typing error and makes sentences look unedited.

Below: a quick rule, clear wrong/right pairs for work, school, and casual writing, step-by-step rewrites, a simple memory trick, and short exercises so you can fix sentences fast.

Quick answer

Use almost (one word) to mean "nearly" or "not quite." Writing all most (two words) is usually wrong and reads like a typo.

Incorrect: I all most finished the presentation.
Correct: I almost finished the presentation.
Tip: If you mean "nearly all," write almost all. If you mean "nearly," collapse into almost.

Core explanation: grammar and when to use almost

Almost is an adverb that modifies verbs, adjectives, and clauses (almost finished, almost empty, almost always). "All most" separates two valid words but doesn't convey "nearly."

almost = single adverb meaning "nearly"
almost all = "nearly all of" (correct: Almost all of the team)
all most = usually a spacing error; replace with almost when you mean "nearly"

Wrong: I all most finished the report.
Right: I almost finished the report.
Wrong: All most students passed the quiz.
Right: Almost all students passed the quiz.

Real usage and tone: formal to casual

Almost works in emails, reports, essays, and quick messages. In formal writing, pick a more precise alternative if needed (nearly, practically, on the verge of).

Formal: I almost completed the audit and will submit it by Friday.
Neutral/email: I almost finished the draft; sending it tomorrow.
Casual/text: Almost there-be home in five.

Usage (work): I almost finished the slides; just polishing the conclusion.
Usage (formal): I almost completed the audit and will submit the summary by 5 PM.
Usage (casual): I'm almost at the cafe-save me a seat!

Work examples: quick wrong/right pairs

At work the two-word error appears in Slack, status updates, or subject lines. Replace with almost to keep a professional tone.

Work - Wrong: I all most finished the quarterly budget; one figure is missing.
Work - Right: I almost finished the quarterly budget; one figure is missing.
Work - Wrong: All most of the team approved the plan.
Work - Right: Almost all of the team approved the plan.
Work - Wrong: I all most uploaded the revised deck to the folder.
Work - Right: I almost uploaded the revised deck to the folder.
Work - Wrong: We're all most ready to launch next week.
Work - Right: We're almost ready to launch next week.

School and academic examples

Students type fast and may split almost into two words. For formal assignments, choose nearly or practically when you need a precise tone.

School - Wrong: I all most finished my literature review but still need one source.
School - Right: I almost finished my literature review but still need one source.
School - Wrong: All most lab groups observed the reaction under the microscope.
School - Right: Almost all lab groups observed the reaction under the microscope.
School - Wrong: She all most understood the theory after the lecture.
School - Right: She almost understood the theory after the lecture.
School - Wrong: I all most completed the problem set; I'll submit tonight.
School - Right: I almost completed the problem set; I'll submit tonight.

Casual examples: texts, posts, and chat

In quick texts or social posts, almost is still one word. "All most" stands out as a typo and distracts from the message.

Casual - Wrong: I'm all most there, be right with you!
Casual - Right: I'm almost there, be right with you!
Casual - Wrong: I all most forgot about dinner plans.
Casual - Right: I almost forgot about dinner plans.
Casual - Wrong: All most everyone was laughing at the joke.
Casual - Right: Almost everyone was laughing at the joke.
Casual - Wrong: We all most made it to the concert on time.
Casual - Right: We almost made it to the concert on time.

Try your own sentence

Test the whole sentence instead of the phrase alone. Context usually makes the right form obvious-say it aloud and listen for one beat: "AL-mohst".

Rewrites: step-by-step fixes and stronger rewrites

Fix in two steps: collapse all most → almost, then check whether a more precise word fits (nearly, just about, on the verge of, almost all).

Minimal fix: collapse into almost.
Stronger rewrite: choose nearly/just below/on the verge of for precision.
When reporting data, prefer Almost all + noun for clarity.

Wrong: I all most finished the project last night.
Right: I almost finished the project last night.
Rewrite (stronger): I nearly completed the project last night; I only need to add the executive summary.
Wrong: She all most passed the exam but missed one question.
Right: She almost passed the exam but missed one question.
Rewrite (stronger): She scored just below the passing mark after missing one question.
Wrong: We all most agreed on the launch date.
Right: We almost agreed on the launch date.
Rewrite (stronger): We were close to agreeing on the launch date, but one department requested more time.
Wrong: All most the committee members objected to the change.
Right: Almost all the committee members objected to the change.
Rewrite (stronger): The majority of committee members objected to the change.

Hyphenation and spacing: why this looks like a typo

No hyphen or space should separate almost when you mean "nearly." The mistake usually comes from typing fast or scanning too quickly.

Spell-checkers often miss it because both all and most are valid words. Read aloud or search your draft for "all most."

Don't write all-most or split almost into two words.
If you mean "nearly all," write Almost all (adverb + adjective).
Read the sentence aloud: if you say it as one beat, write almost.

Wrong: All-most of the students arrived early.
Right: Almost all of the students arrived early.
Wrong: He wrote 'all most' by mistake in the report.
Right: He wrote 'almost' by mistake in the report.

Similar mistakes and quick cheats

Writers mix up pairs like all right/alright, every day/everyday, and altogether/all together. Spotting these patterns reduces other spacing errors.

all right (two words) = acceptable; alright is informal and often avoided in formal writing.
every day (two words) = each day; everyday (one word) = ordinary or common.
all together (two words) = everyone in the same place; altogether (one word) = entirely/completely.

Wrong: Its alright, I all most know the answer.
Right: It's all right; I almost know the answer.
Wrong: She all most goes to the gym every day.
Right: She almost goes to the gym every day.
Wrong: They were all together surprised by the announcement.
Right: They were altogether surprised by the announcement. (or: They were all together when surprised.)

Practice and memory trick

Quick checklist: search, say, fix. The memory trick ties the single-word sound to the correct spelling.

3-step checklist: 1) Search your draft for "all most"; 2) Read the sentence aloud-if it sounds like one beat, write almost; 3) If formal, consider nearly or a more precise phrase.
Memory trick: pronounce almost as one beat-"AL-mohst"-and imagine the letters "mo" glued to "al". If the sound breaks into "all" + "most", you likely typed a space by mistake.

FAQ

Is "all most" ever correct?

Very rarely. Standard English uses almost. You can say "almost all" to mean "nearly all of." Any other use of all + most is uncommon and usually a mistake.

Why does this mistake happen?

Fast typing or thinking of the words separately. Both all and most are valid, so spell-checkers often don't flag the spacing error.

Should I use almost in formal writing?

Yes. Almost is fine in formal writing. Use nearly, practically, or nearly all when you need more precision.

Can a grammar checker catch this?

Many tools catch spacing and context errors, but always do a quick search for "all most" or read the sentence aloud to be safe.

How can I avoid repeating spacing mistakes?

Keep a short checklist of patterns you often mistype (all most, its/it's, every day/everyday) and search long documents for those patterns before finalizing.

Quick fix now

Search your draft for "all most" and replace with almost in most cases. That single change fixes the majority of errors and makes writing cleaner and clearer.
