adjective. thirsty

An adjective for “thirsty” in notes from around 1960 derived from the root √SOK “drink” via *i*-infixion (VT39/11), a process which produced a small class of desiderative words in Quenya, as in “desiring to drink”. See the entry ᴹQ. fauka for earlier and alternate words for “thirsty”.
