  • If you go to strike and look at the etymologies, some of the early senses are quite sensual rather than violent: stroke, rub, graze, etc.

  • Moonstruck. The definitions and etymologies focus on the first syllable and ignore the second. I think there is hidden significance in "struck." The distant silver orb is quiet, tranquil. It doesn't threaten. Then why is a word describing violence appended?

  • I can find dictionary references for both moonstruck and moon-stricken, but moonstrike seems not to have come into being except as the name of a B.B.C. television series. Presumably because only the moon can render people moonstruck, which it just does by striking them.
