Blokes pursuing seabird to be brought into international custody (10)
I believe the answer is:
internment
'custody' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'blokes pursuing seabird to be brought into international' is the wordplay.
'blokes' becomes 'men' (bloke can informally mean a man).
'pursuing' means one lot of letters go next to another.
'seabird' becomes 'tern' (tern is a kind of seabird).
'to be brought into' indicates putting letters inside.
'international' becomes 'int' (abbreviation for international).
'men' after 'tern' is 'ternmen'.
'ternmen' placed within 'int' is 'INTERNMENT'.
Can you help me to learn more?
(Other definitions for internment that I've seen before include "Committal" , "Precautionary measure" , "Locking up" , "Confinement of an enemy national" , "Detention" .)
