pass: [13] Strictly speaking, English has two distinct words pass, although they come from the same ultimate source, and have now virtually merged together again. That source was Latin passus ‘step’, which gave English pace. From it was derived the Vulgar Latin verb *passāre, which came to English via Old French passer. The past participle of the English verb has become past; and other related English words include passage and passenger.

The noun pass ‘mountain defile’ originated as a sense of pace, but since the early modern English period has been spelled (and pronounced) pass, partly through reassociation with French pas, partly under the influence of the verb pass.
