"He was a doctor."
Translation:Ba dhochtúir é.
Yes. However, ba is also the conditional mood of the copula. And it's more likely to be interpreted as that without context.
Anyone know why it is you can't say, 'Bhí sé ina dochtúir' for this question? Thanks!
There is a difference in meaning between:
Ba dhochtúir é
Bhí sé ina dhochtúir
However the English sentence here could be both, so either is acceptable.
