[Middle English diminishen, blend of diminuen, to lessen (from Old French diminuer, from Latin dīminuere, variant of dēminuere : dē-, de- + minuere, to lessen) and minishen, to reduce (from Old French minuiser, from Vulgar Latin *minūtiāre, from Latin minūtia, smallness, from minūtus, small, from past participle of minuere); see mei-2 in Indo-European roots.]
1417, from merger of two obsolete verbs, diminue and minish. Diminue is from O.Fr. diminuer "make small," from L. diminuere "break into small pieces," variant of deminuere "lessen, diminish," from de- "completely" + minuere "make small." Minish is from O.Fr. menuisier, from L. minuere.
