diminish: [15] Diminish is a hybrid verb, the result of a marriage between the now obsolete diminue [14] and the virtually obsolete minish [14], both of which meant ‘make smaller’. Diminue came via Old French diminuer from Latin dīminuere ‘break into small pieces’; it was a compound verb formed from the prefix dē- ‘from’ and minuere ‘lessen’ (source of English minute). Minish came via Old French menuiser from Vulgar Latin *minūtiāre, a derivative of Latin minūtus ‘small’; this, bringing the history of diminish full circle, was an adjectival use of the past participle of minuere. => minute
