Be holding the group of aliens, or foreigners (8)
I believe the answer is:
balinese
'be holding the group' is the definition.
I can't judge whether this definition defines the answer.
'aliens or foreigners' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'aliens' is 'alines' which is within the answer.
The remaining letters 'be' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for balinese that I've seen before include "Islanders" , "policy needs external support" , "Indonesian" , "Foreign language" , "Asian language" .)
