√UM root. “abound; teem, throng; large”
A root appearing in various notes from around 1968 having to do with “large & small”, variously gloss “large”, “abound” and “teem, throng”, along with derivatives like Q. úma- “teem”, Q. umba “swarm”, and Q. úmë “great collection or crowd; throng” (VT48/32; PE17/115). √UM “large” was also mentioned in passing in notes on Variation D/L in Common Eldarin, also from 1968 (VT48/25). This √UM is probably a later iteration of ᴹ√UB “abound” from The Etymologies of the 1930s with derivatives like ᴹQ. úve “abundance, great quantity” and N. ovor “abundant” (Ety/UB). Based on its derivatives, it seems √UM means “large [in quantity]” rather than size.
