• Pronunciation: /ta.i.soː/

Meaning

Exaggerated; grandiose; over-the-top; very great. Used sincerely to mean 'enormous/tremendous,' or ironically to suggest something is blown out of proportion.

A na-adjective and adverb with dual usage: used sincerely, 大層 means 'very great' or 'enormous' (大層な苦労, a tremendous ordeal; 大層嬉しい, enormously pleased); used ironically, it criticises someone for overdramatising or acting self-important. Context and tone determine which sense is intended. Carries a somewhat old-fashioned, colloquial flavour—common in regional speech, period dramas, and narrative storytelling. Also appears as a standalone adverb meaning 'greatly/tremendously.'

Examples

1. 大層なことを言うわりに、実際の仕事ぶりはたいしたことがなかった。 For all the grand things he says, his actual work was nothing particularly impressive.
2. 故郷を離れた日のことを、祖母は大層つらかったと今も語る。 My grandmother still speaks of the day she left her home town as having been enormously painful.

Origin & History
