Synonym discussion
Sense: verb/1
All four words describe reducing something, but each has a distinct flavour. 'Lessen' is the most general term, suitable for any reduction in amount, degree, or intensity — you can lessen a risk, a pain, or a difference. 'Moderate' specifically means to make something less extreme or excessive, often by bringing it to a reasonable level (moderate your tone, moderate your demands). 'Diminish' suggests making something smaller or less important, sometimes gradually (the sound diminished as the train pulled away). 'Restrain' implies holding back or keeping under control through deliberate effort (restrain your temper, restrain spending). 'Bate' today is the most literary and least common of the group. You can lessen the risk but not bate the risk; you might moderate your tone or restrain your temper, but 'bate' would sound deliberately old-fashioned in either context.

Etymology
'Bate' is a shortened form of the verb 'abate', which entered Middle English from Old French 'abatre' (meaning to beat down or fell). The Old French verb traces back to Latin 'battuere', meaning 'to beat'. The falconry sense developed from the image of a bird of prey beating its wings against restraint — the same root image of 'beating' that gave rise to the general meaning of reducing force. For centuries, 'bate' and 'abate' existed side by side, but 'bate' gradually fell out of everyday use except in a few fixed expressions.
