out come (outcome)

Most of the time, use outcome (one word) when you mean "result" or "consequence." Writers sometimes split it into out come by mistake, or they use out + come correctly when out is an adverb and come is the verb (often in inversion: "Out came the winners").

Below are clear rules, quick tests, many concrete wrong/right examples, ready-to-copy rewrites for work, school, and casual contexts, and a short memory trick to stop the split.

Quick answer

Use outcome (one word) for the noun meaning "result." Use out + come (two words) only when out is an adverb and come is the verb-e.g., "Out came the champion." Avoid out-come (hyphen) in modern writing; prefer outcome or a rewrite.

Noun (result): outcome - The outcome was positive.
Verb phrase (direction + verb): out come / out came - Out came the rescued dog.
Hyphen: out-come is almost never used; choose outcome or rephrase.

Core explanation: noun (outcome) vs. verb phrase (out + come)

Outcome is a single noun meaning result or consequence. It behaves like any other noun: it can take determiners, be pluralized (outcomes), and form possessives.

Out come is the adverb out plus the verb come. You see it in actions or inverted constructions: "Out came the sun" or "Out came her phone."

If you can add the or make it plural (the outcome / outcomes), it's the noun outcome.
If the idea is someone or something coming out, use out + come and check tense (out came, out comes).

Noun: Correct: The outcome of the study supports the hypothesis.
Verb-phrase: Correct: Out came the winners to accept their awards.

Spacing test: three quick checks to pick the right form

Run these micro-tests on the full sentence to reveal whether one word or two is correct.

Test 1 (determiner): Can you say "the outcome"? If yes, use outcome.
Test 2 (plural): Can you say "outcomes"? If yes, use outcome.
Test 3 (verb swap): Can you rewrite the clause as " came out"? If yes, use out + come (or "out came" for inversion).

Example (determiner): "We measured the out come." → "We measured the outcome."
Example (verb-swap): "Out come the finalists." → "The finalists came out" (so keep out + come/inversion).

Hyphenation: why out-come is usually wrong

Modern usage treats outcome as a closed compound (one word). A hyphenated out-come looks dated or forced and is rarely correct for the noun.

If you feel a hyphen might help clarity, choose a different phrasing instead (for example, "result-driven" rather than "out-come-driven").

Do not write out-come for the noun; use outcome.
When in doubt, rephrase: "outcome-oriented" or "a plan oriented toward outcomes."

Poor: The out-come-oriented plan. Better: The outcome-oriented plan.
Historic/poetic: Some older texts show out-come, but modern style prefers outcome.

Grammar: pluralization, possessives, and adjectival forms

Outcome is countable: plural is outcomes. Possessives follow normal rules: the outcome's importance, the outcomes' distribution.

Adjectives formed from outcome commonly use hyphens when they modify another noun: outcome-based, outcome-oriented. These are built from the noun, not by splitting it.

Plural: outcomes. Possessive: the outcome's effect; the outcomes' trends.
Adjectival: outcome-based training, outcome-oriented policy (hyphenated when used before a noun).

Plural: Correct: We tracked multiple outcomes across participants.
Possessive: Correct: The outcome's significance was debated.
Adjectival: Correct: An outcome-based evaluation provides clearer metrics.

Real usage and tone: examples for work, school, and casual writing

Use the noun outcome for results in reports, assignments, and messages. Reserve out came / out come for narrative or emphatic action.

Work: formal and metric-driven - outcome for results.
School: academic and clear - outcome for experiment results and conclusions.
Casual: conversational - outcome for results; "Out came..." only for storytelling.

Work-1: The outcome metrics will determine our Q3 priorities.
Work-2: Please summarize the expected outcomes for the pilot.
Work-3 (wrong → rewrite): Wrong: "Attach the out come report." |
Rewrite: "Attach the outcome report."
School-1: The expected outcome of the experiment is reduced latency.
School-2: List three possible outcomes and explain why each might occur.
School-3 (wrong → rewrite): Wrong: "What is the out come of your lab?" |
Rewrite: "What is the outcome of your lab experiment?"
Casual-1: I'll tell you the outcome as soon as I hear back.
Casual-2 (narrative): Out came the cat from under the couch.
Casual-3 (wrong → rewrite): Wrong: "Keep me posted on the out come." |
Rewrite: "Keep me posted on the outcome."

Memory trick and quick habit to stop the split

Mnemonic: outcome = result (one package). Out + come = action (someone "comes" with direction "out"). Think: "Result? → one word. Action? → two words."

Habit: run a find for "out come" (with a space) before you finalize a document. For each hit, run the three tests and apply a rewrite.

Mnemonic: Outcome = result. Out + come = action of coming out.
Habit: Search your draft for "out come" and fix each instance.
Search example: Use Ctrl/Cmd+F for "out come" to find and fix instances quickly.

Similar mistakes to watch for

The same determiner/plural tests and verb-swap tests help with other problem pairs: setup vs set up, into vs in to, outright vs out right. When you see a hyphenated form, check whether modern usage prefers a closed compound or a rephrasing.

Common pairs: setup (noun) vs set up (verb); into (preposition) vs in to (depends on context); outright (one word) vs out right (rare).
Ask: is it a noun? Try "the"/pluralize. Is it a verb phrase? Try swapping to "came out" or "set up."

Setup vs set up: The setup took an hour. / They will set up the equipment.
Into vs in to: Come into the room. / She went in to check the mail.
