再 (zài) means "again" with 6 strokes, radical 冂 (down box), HSK 1 on the new exam.
Pronunciation
Meaning
Primary: again
Etymology
Oracle-bone origin
The oracle-bone graph of 再 shows a fish (or sometimes interpreted as a stack of items) with an added mark, often read as 'one more' added to an existing count. The traditional analysis, following the Shuowen Jiezi, is that it depicts 'one' (一) over 冓 (interlaced pieces), signifying doubling or pairing. Either reading fits the core sense of 'again, one more time'.
Form evolution
Bronze forms keep the stacked or paired structure clearly visible. Seal script tightens this into a rectangular frame with internal cross-strokes. Clerical script regularises the mess of inner lines into the modern shape: a top horizontal, a vertical crossing a 冂 frame, and two internal horizontals, giving the six-stroke 楷书 form.
How the meaning evolved
The original meaning 'a second time, once more' is preserved essentially unchanged in modern Mandarin. From there it extended to 'again, furthermore' in adverbial use (再说 'moreover') and to 'then, and only then' in conditional constructions (吃完再走 'finish eating then leave'). Classical 再 specifically meant 'twice' as opposed to 复 'repeatedly'; this numeric precision has faded in the modern language.
Cultural note
再见 (zài jiàn, 'goodbye') literally means 'see again' and mirrors the structure of European farewells like au revoir or auf Wiedersehen. Learners sometimes confuse 再 ('again, in the future') with 又 (yòu, 'again, already happened'); the tense orientation is the key distinction.
