Take oils out of boiler suit from the Mediterranean port (6)
I believe the answer is:
beirut
'suit from the mediterranean port' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'take oils out of boiler' is the wordplay.
I cannot quite understand how this works, but
'take' could be 'be' (being is a kind of taking) and 'be' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beirut that I've seen before include "Middle East capital" , "Capital city of Lebanon" , "Lebanese capital" , "Lebanon's capital" , "Capital of 21 across" .)
