Grammar
But, like and, is a common transitional word and often begins sentences. When it is used in the middle of a sentence as a coordinating conjunction like and or so, it is not followed by a comma unless the comma is one of a pair setting off a parenthetical expression: His political affiliations make no difference, but his lack of ethics does. The cast is nearly complete, but, our efforts notwithstanding, we lack a star. See also and, so 1. When but is understood as a conjunction and the pronoun following it is understood as the subject of an incompletely expressed clause, the pronoun is in the subjective case: Everyone lost faith in the plan but she ( did not lose faith ). In virtually identical contexts, when but is understood as a preposition, the pronoun following it is in the objective case: Everyone lost faith but her. The prepositional use is more common. However, when prepositional but and its following pronoun occur near the beginning of a sentence, the subjective case often appears: Everyone but she lost faith in the plan. See also doubt, than.

Etymology
Origin of but1

Origin of but-4
Explanation
But is the word that turns a corner in a sentence. If a sentence starts out in one direction, but can change that direction. For example: "I like you, but I never want to see you again." But can mean "however," "nonetheless," and "on the contrary" in three little letters. It's English efficiency at its best. But is short but powerful. But is everywhere but never unnecessary. But sometimes means "just," as in "I'll have but a few of those delicious candies." Grade schoolers might snicker, but the word would need another t to mean your "bottom."
