"answer", n.
[OE. "andswaru", cogn. with OS. "antswôr", OFris. ("ontswer") "ondser", ON. "andsvar", "annsvar", Dan. and Sw. "ansvar", OTeut. "*andswarâ-"; f. "and-" "against", "in reply" + "*swarâ-" "affirmation", "swearing", f. OTeut. "*swarjan", Goth. "swaran", OE. sw rian "to affirm", "swear". The original meaning was thus a "solemn affirmation" (= "formelle Zusage") made to rebut a charge.]
So it's clear that the "w" comes in from the root "swarjan" "to swear" - so "answer" and "swear" share a common source. It's just that the "w" is now silent. I can't help you with when that happened, but many Elizabethan pronunciations were much more literal than now - which is why they were spelled that way ...
