How to say "merger" in Japanese

- 併合へいごうnoun, suru verb, transitive verb, intransitive verbA merger in the sense of joining into one or amalgamation. It is a formal word for things being united, but for company mergers 合併 is usually the word you want.
- 混同こんどうnoun, suru verb, transitive verbHere 'merger' is marginal: 混同 really means confusion or mixing things up, especially mistaking one thing for another. It is seldom the word you want for a business or organizational merger.
- 大同団結だいどうだんけつnoun, suru verb, intransitive verbA four-character idiom glossed as merger or presenting a united front. It refers to formerly divided groups uniting on a grand scale, and is figurative rather than a term for corporate transactions.
- 合体がったいnoun, suru verb, transitive verb, intransitive verbCovers union, combination, coalescence or amalgamation — things physically or structurally combining into one. For company mergers 合併 is more idiomatic; 合体 suits combining bodies or machines.
