How to say "longitudinal" in Japanese
Choosing the right word
- 縦断的じゅうだんてきna-adjectiveA less common but precise term for the technical sense of 'longitudinal': research that follows the same subjects over an extended period, as in a longitudinal study in medicine or psychology.
- 縦型たてがたno-adjectiveReally describes a vertical, portrait-style orientation or format; it matches 'longitudinal' only when that means upright or lengthwise in shape, and it is not the word for the over-time sense of research.
Use 縦断的 for the technical 'longitudinal' of research that tracks the same subjects over time; 縦型 really means vertical or portrait-style, fitting 'longitudinal' only in the loose sense of an upright, lengthwise orientation.
