Run across moon explorer (5)
I believe the answer is:
rover
'moon explorer' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'run across' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'across' becomes 'over' (synonyms).
'r'+'over'='ROVER'
Can you help me to learn more?
(Other definitions for rover that I've seen before include "Itinerant person" , "Vehicle driven remotely over extraterrestrial terrain" , "Wanderer, rolling stone" , "Nomad" , "Wanderer, archery mark" .)
