Another misunderstanding (not a scripture, but a scriptural word): helpmeet (or sometimes you hear people say help mate). Either way, a woman/wife isn't a helpmeet. "Meet" is used as an adjective meaning fit or suitable. The woman is given as a helper - a helper who is fit or suitable (or meet) for him.
A comma would've made it much clearer. "And the Lord God said, It is not good that the man should be alone; I will make him an help, meet for him."
