Is a ways to go correct grammar?

"A ways to go" is grammatically correct in informal spoken English. However, in formal writing, the more grammatically correct phrase is "a long way to go."

Here's why:

* "Ways" is a plural noun meaning "paths" or "methods," while "way" is a singular noun meaning "distance" or "direction." In the phrase "a ways to go," "ways" is used incorrectly as a singular noun.

* "A long way to go" is the standard phrase for expressing that there is a considerable distance to travel or that much work remains to be done.

Example:

* Informal: "We still have a ways to go before we reach the summit."

* Formal: "We still have a long way to go before we reach the summit."

Therefore, while "a ways to go" is commonly used in casual conversation, it's best to stick with "a long way to go" in formal writing and situations.
