ᴹ√KAP root. “leap”
This root appeared in The Etymologies of the 1930s glossed “leap” (Ety/KAP), and was simply a later iteration of ᴱ√KAPA “leap, spring” from the Qenya Lexicon of the 1910s (QL/45). The root appeared in various other places in the 1920s (PE14/66), 30s (PE19/42) and 40s (PE22/102), always with the same meaning. The root itself did not appear in Tolkien’s later writing, but his continued use of derivatives like S. cabed “leap” (S/224) and S. cáfru “*flea” < ✶kamprū (PE17/131) indicate its continued validity.
