## AI Etymology
Experimentation comes from experiment + -ation, from Latin experimentum ('a trial, test, proof'), from experiri ('to try, test'), from ex- ('out') + periri ('to try, attempt'). Morphologically, the account is both compositional and suffixal: ex- and -ation marks the visible structure by which the older base becomes the modern form. In present use, it is used as a noun meaning "the action of trying out new methods or ideas through tests", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes related forms such as experiment, experimental, and experimenter, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin experimentum, Latin experiri, and Proto-Indo-European *per-, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood includes experiment, testing, trial, and research, locating the modern specialization without adding a new origin story.
