experimentally

The word 'experimentally' is built upon the core Latin noun experimentum, meaning 'a trial or test'. This noun itself derives from the verb experiri ('to try, to put to the test'), which is composed of ex- ('out') and a base related to peritus ('experienced'), ultimately from the Proto-Indo-European root per- ('to try, risk'). The suffix -al transforms the noun into the adjective 'experimental', meaning 'of or based on experiment'. Finally, the adverbial suffix -ly, of Germanic origin, is appended to create the modern adverb. Thus, the word's logical journey is from the ancient concept of 'trying something out' to the specific modern sense of doing something in a manner guided by scientific testing and observable evidence.
