Incorrect spelling, explanation: abit isn’t standard English because a bit is a two-word phrase where a is an article and bit is a noun meaning a small amount. English generally keeps a separate from the noun it modifies in phrases like a lot or a little. We have other similar phrases that follow the same pattern, such as a few, a ton, and so on, where a is kept separate from the noun. If abit were to replace a bit, it would break from this consistency, which is why it sounds off.

Correct spelling, explanation: a is an article that always stands separately from the noun it modifies. When you combine them into abit, it disrupts the basic structure of English grammar, where articles and nouns typically remain distinct. In phrases like a bit, the two parts have separate roles – a is modifying bit, and they work together to express the meaning of a small amount. In short, a bit is grammatically correct because it follows the established rule of using an article with a noun, and combining them into abit doesn’t align with the conventional structure of English.
