词源

词源 1
The adjective is derived from Middle English retrograd, retrograde (“of a planet: appearing to move in a direction opposite to the order of the zodiac signs, retrograde; unfortunate”), from Middle French retrograde and Old French retrograde (“of a celestial object: appearing to move backwards; moving backwards; reverse; palindromic; opposed to change”) (modern French rétrograde), and from their etymon Latin retrōgradus (“of a celestial object: appearing to move backwards”) (compare Late Latin retrōgradus (“reverse; palindromic”)), from retrō (“back, backwards; behind; before, formerly”) + gradus (“pace, step”). By surface analysis, retro- + -grade.
The adverb and noun are derived from the adjective.
词源 2
From Middle French retrograder (“to (cause to) go back, return; to (cause to) move backwards; of a celestial object: to show retrograde motion; to date to an earlier period”) (modern French rétrograder), and from its etymon Latin retrōgradī (“to go or step back or backwards; of a celestial object: to show retrograde motion”) (compare Late Latin retrogradare, retrogradari, retrogredere), from retrō (“back, backwards; behind; before, formerly”) + gradior (“to step, walk; to advance, go”) (ultimately from Proto-Indo-European *gʰredʰ- (“to go; to walk”)).
