Conjugation of Basic VerbsTake away the -us ending and add these to the stem for each form:
ona - nothing
sou - u
thallus/nuraa - ar
bolûr - ast
dh

l - ôn
ad gwatus - to seeona gwât - I see
sou gwatu - you see (singular and plural)
thallus/nuraa gwatar - he/she sees
bolûr gwatast - we see
dh

l gwatôn - they see
Spelling rules dictate that the core vowel of the verb, the A, needs a circumflex in the ona form - without it, it is indicated that the vowel is short, which it isn't, so there's just that one little spelling change.
A similar spelling change is in demand for verbs with double consonants:
ad shattus - to fightona shat - I fight
sou shattu - you fight (singular and plural)
thallus/nuraa shattar - he/she fights
bolûr shattast - we fight
dh

l shattôn - they fight
A word can't end in a double consonant, so... that's why this spelling change is also necessary in the ona form.
Verbs with more than one consonant (that aren't the same) separating the core vowel and the -us ending don't go through any special spelling changes in the ona form.
ad fhaltus - to walkona fhalt - I walk
sou fhaltu - you walk (singular and plural)
thallus/nuraa fhaltar - he/she walks
bolûr fhaltast - we walk
dh

l fhaltôn - they walk
ad râdhus - to hurt, painona râdh - I hurt
sou râdhu - you hurt (singular and plural)
thallus/nuraa râdhar - he/she hurts
bolûr râdhast - we hurt
dh

l râdhôn - they hurt
