Most attested Adûnaic pronouns appear as prefixes to verbs. When a pronoun is the subject of a verb, it is prefixed directly to the verb form. For example, the Adûnaic feminine singular pronoun is hi “she” and the aorist form of the verb kalab- “to fall” is kalba “falls”, so “she falls” in Adûnaic would be hikalba (SD/247).

There appear to be several circumstances in which a pronominal-prefix can be used with verbs.

1) The pronominal-prefix could be the only subject:

• usaphda “he understood” (SD/421)
• bâ kitabdahê “Don’t [you] touch me!” (SD/250)

2) There can be a separate subject noun in the normal-case. When the subject is in the normal case, the pronominal-prefix is always required (SD/429):

• adûn izindi batân tâidô ayadda “the road west [it] once went straight” (SD/247)
• Anadûnê zîrân hikalba “Númenor the beloved she fell (down)” (SD/247)

3) There can be a separate subject noun in the subjective case. When the subjective case is used in combination with a pronominal-prefix, the subject is emphatic (SD/429):

• kadô Zigûrun zabathân unakkha “and so Sauron he came humbled” (SD/247)
• bârun ukallaba “it was the lord who fell” (SD/429)

The pronominal-prefix is optional if the subject noun is declined into the subjective case. Where omitted, the subject is not emphatic:

• bârun kallaba “the lord fell” (SD/429)
• Êruhînim dubdam ugru-dalad “the Children of Eru fell under shadow” (SD/247)

Apart from the subjective case, the only other known situation where the pronominal prefix can be omitted is with passive-verbs, which have no subject.
