Grammar & Usage

verb phrase

neutral

How it works

This phrase is composed of the noun 理由 ('reason'), the direct object particle を, and the suru-verb 詮索する ('to investigate/pry into'). While 詮索 literally refers to searching out or inquiring into something thoroughly, it often carries a negative connotation of being nosy or inappropriately digging into personal matters. It conjugates as an irregular suru-verb (e.g., 詮索しない, 詮索して, 詮索される).
