yaa

The reference analyzes yaa as ayo fused with baa/ayaa. A focused subject takes no ordinary short subject pronoun and selects reduced agreement. If someone else performs the action, that subject's pronoun and agreement remain.

Compare yaa sawiraya guriga, asking who draws, with yaa aad aragtaa, asking whom the listener sees. Reduced sawiraya belongs to subject focus; full aragtaa agrees with aad. Prepositions remain with the predicate: la supplies company in a with-whom question.

Answers focus the identified participant. With a focused subject and noun predicate, use reduced ah; after an adjective, omit reduced ah. These patterns describe affirmative focused questions. Negative questions require aan and reduced subjunctive formation, rather than simple insertion of ma into every yaa frame.
