What does banisher mean?
A banisher is a person — or, figuratively, a force — that banishes: that formally expels someone from a country, community, or position, or drives something unwanted away. The word is an agent noun built on the verb banish, in the same way that punisher is built on punish, and it inherits the verb's serious, weighty connotations of exile, authority, and loss. In historical writing a ruler might be described as a banisher of rivals or heretics; in everyday figurative use, a cleaning product might be praised as a banisher of stains, or a good night's sleep as a banisher of fatigue. Though far less common than banish or banishment, banisher is a useful label when the emphasis falls on whoever or whatever wields the power of expulsion rather than on the act itself. Its rarity gives it a slightly formal, literary flavor.

Etymology of banisher
Banisher derives from banish, which entered English in the early modern period from French bannir, itself from a Germanic root behind the medieval 'ban' — a public proclamation commanding or forbidding something. That same root gave English the words ban and banns, and, through Latin borrowing, abandon. Banisher arose as a straightforward agent noun in English, parallel to formations like punisher and furnisher.
