to raise a tough question
❓🧱 chū nán tí =出 out + 难 difficult + 题 question — toss out a hard one
You pull out (出) a difficult (难) question (题) and drop it on someone. Like lobbing a brick of a problem — hence the phrase means to pose a tough challenge or awkward question.
出 — foot 止 emerging from enclosure 凵
出 is a pictograph showing a foot or plant stepping out of a hollow or enclosure, depicting the act of going forth. The original sense of 'coming out' or 'emerging' has remained stable since oracle bone script. It now broadly means 'to exit, go out, or produce.'
难 — 又 (right hand) + 隹 (short-tailed bird)
Originally written with 堇 (clay) plus 隹 (bird), 難 depicted a rare bird and was borrowed to mean 'difficult.' The modern simplified form replaces the left side with 又 (hand). The phonetic role of the original left component gave the reading nán.
题 — page radical 頁 + 是 (phonetic)
题 is a phono-semantic compound. The right side 是 gives the sound (shì→tí), while the left 頁 (simplified 页, 'head/page') carries the meaning, since titles and topics were written at the top of a page. Original sense was 'forehead,' later extended to 'title, topic, problem.'
