moom it dina ñow – he also will come

moom – in this sence means ‘he/she‘ (emphatic form) but can also mean ‘to own‘.
it/itam – also (as a suffix ‘-it‘ indicates ‘again‘; it can also be a suffix for the result of an action – added to a verb root. Ex. damma ‘to break‘. dammit ‘pieces‘).
dina – (di + na); di indicates a future action “he will“; di + noun makes a positive statement (he is, etc.); di as a prefix to –oon (doon) = past completed, –aan (daan) = past habitual
ñow – to come/arrive; can also mean ‘to be sharp‘ (sometimes written as ñaw)
