紧
jǐn · HSK 3
tight
🔒 紧 = 又 (hand) + 糸 (silk thread) — a hand pulling thread taut
The bottom 糸 means silk/thread and the top contains 又 (a hand). A hand pulling on thread makes it tight — hence tighten, tense, strict. Extended to 'hard up' for money (finances pulled tight).
紧 — 臣 minister + 又 hand on top + 糸 silk below
Originally written 緊, this character combines 臤 (a hand 又 grasping firmly, with 臣 as phonetic) over 糸 'silk thread'. The image is of silk threads pulled taut by hand, giving the core meaning 'tight, taut'. From there it extended to 'urgent' and 'pressing'.
