jack/jack-/-jack
although the word, prefix, and suffix "jack" came from Jacob and often meant a man/boy, they have come to refer without any particular gender overtones to certain tools (for example, bootjack, hydraulic jack, jackknife), plants and animals (jack-in-the-pulpit, jack mackerel), nouns (apple jack, blackjack, jackpot), verbs (ball the jack, hijack), and adjectives (crackerjack). These can be used as they are, but one wonders: has any woman's name ever influenced dozens of words?
