Pronunciation note

The pronunciation of irrelevant [ih-rel-uh-vuh nt] /ɪˈrɛl ə vənt/, as [ih-rev-uh-luh nt] /ɪˈrɛv ə lənt/, as if spelled irrevelant, is the result of metathesis, the transposition of two sounds, in this case, the [l] /l/ and the [v] /v/. Relevant, the base word, is occasionally subject to the same process. Analogy with words like prevalent and equivalent may play a role. A similar reordering of the [l] /l/ and [v] /v/ consonant sounds, althought not a strict one-to-one metathesis, can be heard for Calvary [kal-vuh-ree] /ˈkæl və ri/ when pronounced [kav-uh l-ree] /ˈkæv əl ri/. Here the transposition is reinforced by the existence of the familiar word cavalry. Unabridged Based on the Random House Unabridged Dictionary, © Random House, Inc. 2019
