(MO to Lieven, 1/09/2012): Words for bricklayer, roof maker, plumber, and so on are all based on the verb mutlh, meaning "construct, assemble, put together". Someone who does this, then, is a mutlhwI'. [...] The idea is that a mutlhwI' puts things together. ... If you did say tlhIm mutlh ("he/she assembled a carpet"), that would mean there were pieces of fabric (or squares of carpet?) that got put together (sewn together?) to make a carpet or rug.
