English explorer with fine hat (6)
I believe the answer is:
fedora
'hat' is the definition.
(I know that fedora is a type of hat)
'english explorer with fine' is the wordplay.
'english' becomes 'E' (abbreviation).
'explorer' becomes 'Dora' (Dora the Explorer, children's TV character).
'with' is a charade indicator (letters next to each other).
'fine' becomes 'f' (abbreviation in pencil classifications).
'e'+'dora'='edora'
'edora' put after 'f' is 'FEDORA'.
(Other definitions for fedora that I've seen before include "Or fade away with man's soft felt hat" , "Brimmed hat with creased crown" , "Felt hat with a creased crown" , "Type of hat" , "Felt hat much loved by 1930s gangsters" .)
