Talk:κακκάω

PIE did not have geminate stops. I dont think this root ever existed. It may be a nursery word, but I wouldnt go to the bother of reconstructing an actual PIE root for it and expecting it to obey sound changes. See Kacke. For that matter PIE may not have even had an /a/ vowel either. Lollipop (talk) 02:11, 27 May 2017 (UTC)
