Did he sail across to central America? (5)
I believe the answer is:
rover
'did he sail' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'across to central america?' is the wordplay.
'across' becomes 'over' (synonyms).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'central' means to look at the middle letters.
The centre of 'america' is 'r'.
'over' after 'r' is 'ROVER'.
Can you help me to learn more?
(Other definitions for rover that I've seen before include "Pirate; dog's name" , "Vehicle driven remotely over extraterrestrial terrain" , "Wanderer, archery mark" , "gypsy" , "A vagrant" .)
