Intrinsically international life for this long-distance flyer. (4)
I believe the answer is:
tern
'this long-distance flyer' is the definition.
'tern' can be an answer for 'flyer'. I am unsure of the 'this long-distance' bit.
'intrinsically international life' is the wordplay.
'intrinsically' indicates the answer is hidden within the clue.
'TERN' is hidden within 'international life'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tern that I've seen before include "Sea bird, a small gull" , "Seabird, sounds like become sour" , "Gull-like sea bird" , "Fork-tailed relative of the gull" , "Seagull" .)
