Ahead and a head sound exactly the same, but they have completely different meanings and grammatical functions. Ahead is usually an adverb meaning “in front,” “forward,” or “in the future.” A head is simply the article a followed by the noun head, meaning one person’s or animal’s head.
For example, “There is a long road ahead” uses ahead to talk about what is in front or in the future. In contrast, “The doctor examined a head in the medical illustration” uses a head as two separate words. Knowing whether you mean a position, direction, future time, or the physical body part will help you choose the correct form.
Quick Answer
Ahead is one word and usually means in front, forward, or in the future. A head is two words: a is an article and head is a noun. For example, “We have a long journey ahead” and “The statue has a head.”

The solution is to look at the meaning and grammar of the sentence.
