Etymology: "Irrefusable" is formed from the prefix "ir-", meaning "not", attached to "refusable," which itself comes from "refuse" plus the suffix "-able," meaning "capable of being." Put together, the word describes something so compelling or so forceful that it cannot be declined. The prefix is the same negating "in-" that appears in words like "irrational" and "irregular." English uses "ir-" in front of words beginning with "r" because "in-" would sound awkward there, so the spelling adjusts to the sound. The result is a straightforward compound: the negation of a word already built from a verb and an ability suffix.

Synonyms: unavoidable, inescapable, indisputable
