I thought I learned at one point that “kaka” (poop) was one of the earliest proto-Indo-European words [0] and think it is present in many languages but “all” is a pretty high bar.

Fun thing I only recently realized, that's what the Gremlins are calling Gizmo in the movies (and just shouting in general in the recent cartoon). Apparently that word is cross-species.

In Norwegian this word is not recognized. Norwegians hear it as «kake» (kAh-keh), cake.
