Relating to or characterized by diminution; involving a reduction or decrease in size or quality.
From Latin 'diminutus' (diminished) plus the adjectival suffix '-al.' This formation follows the pattern of creating adjectives that describe relationship to or association with a concept.
This is a rare, technical word that linguists and philosophers might use to describe 'diminutal processes' in language or logic, but it's the kind of word that exists more in specialized texts than everyday speech!
