A terribly important word today, túm /tuːm/ goop, goo, mush. Basically, any viscous substance you're not too happy to be encountering.
Túm mai úri talo vukai!
goop AD just.now walk FINAL.PRT
I just stepped in some goo!
The final particle vukai is rather like Na'vi's ‹äng› infix. It indicates the speaker is displeased in some way with the state of affairs described.
Vura túm ën sen nen nulo?
what mush this bowl LOC lie.PFV
What mush is in this bowl?
This may not seem like a brilliant example sentence, but it does indicate that túm lies, rather than sits or stands, in a location.
