Expert writing Tips

Best practice

Avoid using "a most likely" in formal writing; instead, use "most likely" without the article "a". This is grammatically correct and more widely accepted.

Common error

The phrase "a most likely" often arises from a misunderstanding of how adverbs function. "Most likely" already acts as an adverb modifying a verb, so adding an article is grammatically redundant and incorrect.
