How “cé” works
Cé stands on its own before a noun or a name: Cé tusa? Before é, í and iad it puts an h in front: cé hé, cé hí, cé hiad. Before a verb it is followed by a, and the verb gets a séimhiú: cé a bhris, cé a chonaic.
“Cé” in questions
Other question words
Who in Irish (cé): the questions people ask
When is it cé and when is it cé a?
Use cé a when a verb follows: Cé a rinne é? Use cé on its own before a pronoun or a name: Cé tusa?, Cé hé Seán?
How do you say who is that in Irish?
Cé hé sin? for a man and cé hí sin? for a woman. For more than one person, cé hiad sin?
Why is it cé hé and not cé é?
Cé puts an h in front of the pronouns é, í and iad. It is the same h that na puts before a vowel in na húlla: cé hé, cé hí, cé hiad.
