Why does dinnéar take a h here? I thought dntls applied?
Not dntls in this case, but dts — nevertheless, it should be don dinnéar.
Why is the answer given as "don dhinnéar" if "don dinnéar" is correct? Are both answers acceptable?
Don dhinnéar is incorrect. Refer to teanglann.ie and also to the dntls rule. I was marked incorrect for writing 'don dinnéar' which actually the correct answer.
don ends with n dinnear starts with d + h ?
Why isn't "Ceannaíonn sé bia le haghaidh an dinnéar" accepted? Doesn't it mean the same thing?
