Latitude for fellow with style (6)
I believe the answer is:
leeway
'latitude' is the definition.
(I've seen this before)
'for fellow with style' is the wordplay.
'for fellow' becomes 'lee' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'style' becomes 'way' (synonyms).
'lee'+'way'='LEEWAY'
Can you help me to learn more?
(Other definitions for leeway that I've seen before include "Margin, latitude, room" , "Room for free movement" , "Flexibility" , "Margin of tolerance" , "Room to manoeuvre, latitude" .)
