"Táim i mo chodladh" unfortunately gets marked as an error here. I guess it's because it means "I am sleeping" as opposed to "I sleep", and the course seems to insist generally on making the distinction between those two tenses.
Táim i mo chodladh - "I'm asleep" Codlaím sa seomra breise - "I sleep in the spare room" Codlaím ar nós linbh - "I sleep like a baby" "Cad a dhéanann tú ag deireadh na seachtaine?" "Codlaím!" - "What do you do at the weekend?" "I sleep!"
