Here are some answers to the exercises. The English translation is my own; the Irish is the original Irish from Abairtí.
D'éirigh Seán go moch ar maidin inné. Nigh sé a aghaidh agus a lámha. Chuir sé a chuid éadaigh air. Chíor sé a ghruaig. Dúirt sé a phaidreacha. Ansin thánig sé anuas an staighre agus d'ith sé a bhricfeasta.
Seán rose early in the morning yesterday. He washed his face and his hands. He put on his clothes. [Lit: He put his portion of clothes on him.] He combed his hair. He said his prayers. Then he came down the stairs and ate his breakfast.
Síle ate a big breakfast today. First she ate a dish of porridge. Then her mother gave her a cup of tea. Síle put milk and sugar in it. She took a piece of bread and she put butter on it. She ate and drank her fill.
D'ith Síle bricfeasta mór an maidin inniu. D'ith sí mias leitean ar dtús. Ansin thug a máthair cupán tae di. Chuir Síle bainne agus siúcra ann. Thóg sí píosa aráin agus chuir sí im air. D'ith sí agus d'ól sí a sá.
