Next to evaporate, evaporation

[foxcatdog]

Epic Letic: ʃɛ̃ʃɛ̃ũ or ʃũʃɛ̃ũ “to evaporate” probably a partial reduplication of an unattested ʃɛ̃ũ "to dry" which would be cognate with sĩ or sũũ in 2 more politically important dialects. Ultimately from the root *ciwã which ultimately derives from *kʲiwam which combines the word for water and an unknown prefix seen also in *kʲize "felled horn" from *ze "antler/horn/spike" which is reflexed in rere "bull animal" and ren "bone" which later semantically shifts to blood > vitality > virility (by now wẽ or mẽ) (note in many dialects it stays just as blood the original "bone" meaning is only attested as a borrowing to the north where its cognate is de "trap"). Also *ze is reflexed in the languages southern relative as *je "trap" *seje "scale" (which is just its reduplicated reflex), *seni "horn" and *seseni "spike" which are the unreduplicated and reduplicated forms + *ni a nominal to nominal intensifier.

Next: Bottom/Solution
This is in the sea metropolis dialect t́ɛ̃ "solution" from original tœr “buttock” and t́ɔ̃ɔ̃ "buttock now rather literary or poetic" from original tœ̃œ̃n “tail” both of which derive from the same root *tońa ultimately from *donja “bottom” which is often reflexed as an adposition in other branches. Also see nɛnɛ or nɛjø "bottom also a preposition meaning under" deriving from possible reduplication of a suffix -nɛ "down" or the same suffix + -ɣø "end" through the more expected form is nɛhø

Next inspire

[foxcatdog]

cae “to breathe” could be nominalised as caewa but you would probably use maí wind+dim for this.
