√MITH root. “grey”
Tolkien introduced the root ᴹ√MITH in The Etymologies of the 1930s as a blending of ᴹ√MIS² “*wet” and ᴹ√KHITH “mist, fog”, with the derivative N. mith “white fog, wet mist” as in N. Mithrim “*Mist Lake” (Ety/MITH, RINGI; EtyAC/MITH). As a later addition to this entry Tolkien wrote the adjective N. mith “grey”, and that was the more common use of this word in Tolkien’s later writings. In a 1955 letter to David Masson Tolkien specified that “usage suggests that MIÞ- is paler and whiter, a luminous grey” (PE17/72).
