Bargin

Bargin is not a standard entry in English dictionaries. In most contexts, it is a misspelling of bargain, a word with several related senses. As a noun, a bargain can mean something bought at a lower price than usual, or more broadly, an agreement or compromise between parties. As a verb, to bargain means to negotiate the terms of an agreement or price. The phrase to strike a bargain is common in everyday usage.

Because bargin lacks an established meaning, it is usually corrected to bargain in edited text. When encountered in writing, it is prudent to assess whether the intended sense concerns a good deal or a negotiated arrangement. If the capitalized form “Bargin” appears, it may indicate a proper noun—such as a surname or a place name—but such uses are rare and not widely documented.

Summary: the standard English term related to the concept of a sale or negotiation is bargain; bargin is typically a misspelling or an idiosyncratic proper noun rather than a separate lexical item.
