Deliberately concealed there's no initial sense in Ulster-Irish alternative (8)
I believe the answer is:
ulterior
'deliberately concealed' is the definition.
'ulterior' can be an answer for 'concealed' (thesaurus). I am not sure about the 'deliberately' bit.
'no initial sense in ulster-irish alternative' is the wordplay.
I cannot really understand how this works, but
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is located in the answer.
'irish' could be 'ir' (abbreviation) and 'ir' is located in the leftover letters.
This may be the basis of clue (or it may be nonsense).
'there's' is the link.
Can you help me to learn more?
(Other definitions for ulterior that I've seen before include "'Deliberately concealed, motive say (8)'" , "Beyond what is apparent" , "rather more than is apparent" , "Deliberately concealed, motive perhaps" , "Situated beyond" .)
