The word "trialled" is derived from the noun "trial", which originated from the Old French word "trial" or "triail", meaning an examination or testing of something. The Old French term was further derived from the Latin word "trialis", which referred to things related to the number three. This connection to number three might have existed because trials at the time were often composed of three points of view or three individuals coming to a decision. Over time, the noun "trial" evolved into a verb form, "to try", and the past tense and past participle form became "trialled" in some variants of English.
