To make a sound or speech pattern more consonant-like, or to bring something into agreement or harmony.
From 'consonant' (sounding together, agreeing), from Latin 'consonare' (to sound together), + the verb suffix '-ise/-ize'. A linguistic or technical term.
This word rarely appears because English prefers 'harmonize' or 'align,' but it shows how linguists sometimes create verbs from every adjective—consonantise is like a ghost word that almost exists.
