How to say "geometric" in Japanese
Choosing the right word
- na-adjectiveA katakana borrowing of the English word, covering the general sense of 'geometric', as in describing shapes or patterns; it is less common, so it is not automatically the word you want.
- 幾何級数的きかきゅうすうてきna-adjectiveCovers only the mathematical sense of 'geometric', describing increase like a geometric progression, where each term is multiplied by a fixed ratio; it is less common and does not serve the general descriptive sense.
Use 「ジオメトリック」 for the general, non-mathematical sense of 'geometric', and 幾何級数的 only for the mathematical sense of geometric progression or growth; both are relatively uncommon in Japanese.
