• Synonym大半たいはんNeutralEveryday word for the greater part, well beyond half; also serves as an adverb. More colloquial than 「過半」.
• Synonym大部分だいぶぶんNeutralPoints to the majority portion, close to all of it, with an emphasis on quantity or proportion. More everyday than 「過半」.
• Synonym大方おおかたWrittenWritten/formal prose. Covers the greater part but also works as an adverb meaning roughly or probably, so its range is broader than 「過半」.
• Related大多数だいたすうNeutralSuggests nearly all — a share far beyond half — so the degree is stronger than 「過半」.
• Related多数たすうNeutralStresses a large number, not necessarily over half — unlike 「過半」, which pins down more than half exactly.
• Related絶対多数ぜったいたすうFormalFormal political term for votes or seats exceeding half in an election.

Use 「過半」 in written prose for more than half, often as 「過半を占める」. For votes and seats say 「過半数」; for well beyond half, 「大半」 or 「大部分」, and 「大多数」 for nearly all. 「多数」 only says the number is large; 「多数派」 and colloquial 「マジョリティー」 name the bigger group; 「絶対多数」 and 「絶対過半数」 are formal election terms; 「少数」 is the opposite.
