Cairteal gu dhà -versus- a bheil e dà uair dheug
In a practice quiz I had these two phrases. I'm wondering why "dhà" is used in one and "dà" is used in the other.
Does this also mean you would say "cairteal gu dhà uair dheug" and "a bheil e dà uair"?
Where does the lenition come from on dà? Would "leth uair an dèidh" ( or "cairteal an dèidh") be followed by dà or dhà?
two itself loves to lenite other words, but it seems like if there is nothing for it to lenite then it lenites itself. so ''there are two'' would be ''tha dhà ann'' but there are two dogs would be ''tha dà chù ann'' for your question, the answer would be ''leth uair an dèidh dhà''
