Actually in the male dominated world of yesteryear the original word was in fact analybro but this was difficult to pronounce as when spoken it sounded like a drunk's last unfinished word before sleep and snoring. Alternatives were tried like analymom (sounded too much like a disease) and analydad (an exotic arabic country?). Eventually the lights went on in the change word dept and analysis was born.
and the plural of this word, contrary to common opinion, is in fact analysisters.
