a prefix taken from Latin that attaches to the start of nouns and adjectives to mean 'almost' or 'nearly' — used to describe something that comes very close to being the thing named but falls just short of it; for example, a peninsula is almost an island (nearly surrounded by water), and the penultimate item is almost the last one (one before the final).
A peninsula, from pene- (almost) and insula (island), is land almost surrounded by water.
半島 (peninsula) 一詞來自 pene-（幾乎）和 insula（島嶼），指幾乎被水包圍的陸地。
prefix pene- + insula 'island' → peninsula

- semi-
Also means 'half' or 'partly', but is more common and attaches to a wider range of words, including everyday English (semicircle, semifinal).
- quasi-
Means 'seemingly' or 'partly', often used before nouns or adjectives to suggest something resembles but is not the real thing (quasi-official, quasi-scientific); more flexible than pene-.
- sub-
Can mean 'under' or 'almost' in some Latin compounds (subarctic = almost arctic), but its primary sense is 'below' rather than 'nearly'.

用法筆記
Only attaches to words of Latin origin, so it does not combine freely with native English or Germanic roots. The resulting compound is typically formal or technical in tone — learners will encounter it most often in geography (peninsula), astronomy (penumbra), and academic sequencing (penultimate).
