In the third example it would be the interrogative pronoun "was."
The verb may be preceded by an affirmative, a negative, or an interrogative particle.
In a simple interrogative sentence the introductory particle before the verb is a, and the positive answer consists in a repetition of the verb; a ddaw Dafydd ?
As in Bantu, the verb presents a multiplicity of forms, including one present, three past and future tenses, with personal endings complete, passive, interrogative, conditional, elective, negative and other forms, each with its proper participial inflexions.
Quien, the interrogative pronoun which has taken the place of the old qul, seems to come from q u e rn.
