In this way men are trained for the sea (13)
I believe the answer is:
mediterranean
'the sea' is the definition.
(Mediterranean is an example)
'in this way men are trained' is the wordplay.
'men are trained' anagrams to 'MEDITERRANEAN'.
However, I am unsure how this is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for mediterranean that I've seen before include "Inland sea" , "Sea linking three continents" , "Sea south of Europe" , "Sea north of Africa" .)
