codwm

fall, Irish tuitim, Old Irish tuitim, inf. tutimm, acc.pl. totman, also tothimm, *tod-tim, Gadelic root - tim-, Welsh codwm, a fall (cf. Irish cudaim), codymu, cadere, Cornish codha; cf. English tumble, Greek tomber, fall. Usually explained as *to-fo-thét-, from théid, which would naturally be tuid in Gaelic, even granting that the crasis of - ofothé- simply landed in - ui-, not to mention the inf. in preserved m ( tuiteam). Root tud (Thurneysen); to-ud = think.
