helpmate has the recorded history: An alteration of helpmeet, itself a misreading of the biblical phrase 'an help meet for him' (Genesis 2:18), refashioned with mate ('companion'). The form is also shaped by later English word-formation, since shortening, alteration, or polite substitution can be as important as direct inheritance. In present English, the noun sense is "a companion and helper, especially a spouse", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as helpmeet, help, and mate. Its semantic neighborhood includes companion, partner, spouse, and consort, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Old English help and Middle English mate.
