The verb's way of dressing differently for every tense, person, and mood.

means The set of different forms a verb takes to show tense, person, and number — like 'walk,' 'walks,' 'walked,' and 'walking' all being the same verb in different outfits.

from From Latin conjugare, 'to yoke together' — con- ('with') plus jugare ('to join,' from jugum, 'yoke'). The Romans used it for joining in marriage or partnership; grammarians borrowed the image for verbs 'yoked' to their various endings, each form bound to the same root stem.
