experimental

The word 'experimental' is built upon the noun 'experiment', which itself originates from the Latin experimentum, meaning a trial, test, or proof. This Latin noun comes from the verb experiri, "to try, test", which is a compound of ex- ("out of") and a base related to peritus ("experienced, skilled") and periculum ("trial, danger"). The literal sense is "to try out, to test something to gain knowledge from it". The suffix -al was added in Middle English, borrowed from Latin -alis, to transform the noun into an adjective. Thus, the modern meaning logically evolved from the core idea of "relating to the act of trying something out" to describe both the scientific process of testing and anything innovative or provisional that is undergoing such a trial phase.

Structure: ex (out) + peri (try) + mental (adjective suffix) - ex: Latin origin, meaning "out of, from". A prefix indicating outward movement or separation. - peri: A variant of the Latin root per- (to try, attempt), found in words like periculum (danger, trial). It is the core root of the word "experiment". - mental: An English adjectival suffix derived from Latin -mentum (instrument, medium of action) via Old French -ment, used to form adjectives meaning "relating to, resulting from".
