Etymology: This adjective form traces back to a verb rooted in the concept of making something irrational. The base verb, "irrationalise," appeared in English likely during the 19th or early 20th century, as part of a broader trend to create verbs by adding the suffix "-ise" (or "-ize") to adjectives, especially those with Latin or Greek origins. The verb means to render something irrational—depriving it of reason or logical coherence. The core of the word stems from "irrational," itself formed from the prefix "ir-" (a variant of "in-," meaning "not") attached to "rational." "Rational" comes from Latin "rationalis," which derives from "ratio," meaning "reason" or "calculation." Thus, "irrational" literally means "not rational," or lacking reason. Adding the suffix "-ise" transforms the adjective into a verb, indicating the action of causing or becoming irrational. The further addition of the past tense "-ed" suffix creates the past participle or adjective form, which describes something that has undergone this process. This layered construction illustrates how English builds complex forms through successive affixation. While the verb and its derived adjectival form remain relatively rare and technical, they reflect a pattern of linguistic productivity where abstract qualities are verbalized and then adjectivized to express nuanced states or actions related to reason and logic.
