μάσσω

Etymology
There are two prevailing theories, based on which velar stop in the word's derivatives was the original:
 * If, then from , from . Cognates include 🇨🇬 (whence 🇨🇬), 🇨🇬, 🇨🇬, and perhaps 🇨🇬, 🇨🇬, 🇨🇬,
 * If, then from , and cognate with 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬.

It is worth noting that these two roots appear to have been confused in various branches (as many of the cognates listed for have alternatively been derived from, though for all except the Germanic, this is phonetically implausible). It is possible that forms in or derived from κ (such as and ) are from  and suppletive with the forms in γ (such as ), which would be from.
