combine together (combine)

Most of the time, "combine" already means "bring together," so adding "together" is redundant. That repetition is harmless in speech but weakens formal writing.

Below: a short rule, clear wrong/right pairs, context-specific rewrites (work, school, casual), quick-edit steps, a memory trick, punctuation notes, and FAQs.

Quick answer

Drop "together" after "combine." Use "combine" alone. If you need a different nuance, choose a more precise verb: merge, pool, consolidate, bring together, synthesize, aggregate.

"Combine" already implies bringing parts into one → delete the extra word.
For physical gathering, use "bring together" or "gather."
In speech it's common; in emails, reports, and essays prefer the concise form.

Core explanation: why it's redundant

"Combine" is transitive and implies joining parts into a whole. Adding "together" repeats the same idea without adding meaning.

Fixes are usually simple: delete "together" or swap to a verb that matches the exact action (merge for systems, synthesize for ideas, aggregate for data).

Combine = mix or join parts into one.
Together = with one another or in one place - already built into "combine."

Wrong: Let's combine together all the ingredients for the cake.
Right: Let's combine all the ingredients for the cake.
Wrong: They combined together the datasets before analysis.
Right: They combined the datasets before analysis.

Real usage and tone

Writers add "together" for emphasis, rhythm, or habit. That's fine in casual speech; in formal writing aim for precision. If repetition is used as a rhetorical device, make sure it's intentional.

Casual: common and forgiving - "Let's combine together, then decide."
Formal: remove padding - prefer concise verbs and domain-specific alternatives.
Technical: choose precise verbs (merge, integrate, aggregate) to avoid ambiguity.

Spoken: "Combine together what we have and see if it fits." - okay in conversation.
Rhetorical: "We must combine together our strengths." - better as "unite" or "pool."

Fix your sentence: quick editing steps

1) Delete "together." If meaning is unchanged, stop. 2) If nuance shifts, pick a stronger verb. 3) If you mean physical gathering, use "bring together."

Delete first. If the sentence feels wrong, swap the verb: merge, pool, consolidate, bring.
Prefer one precise verb over a verb plus a redundant modifier.

Rewrite:
Original: "We'll combine together the Q1 and Q2 reports." → "We'll combine the Q1 and Q2 reports." → If integration is meant: "We'll merge the Q1 and Q2 reports into a single summary."
Rewrite:
Original: "Combine together the samples and label them." → "Combine the samples and label them." → If you mean gather them: "Bring the samples together and label them."
Rewrite:
Original: "They combined together their resources." → "They combined their resources." → For clarity: "They pooled their resources."

Quick-edit test: delete the suspect word. If meaning stays the same, the word was redundant.

Scan for verbs followed by repeating words (combine together, join together). Delete the second word and reread.
Watch other repeating pairs: repeat again, end result, close proximity.
If deletion makes the sentence awkward, swap the verb: bring together (physical), merge (systems), pool or synthesize (ideas/data).
