Sport gun Republican avoids (4)
I believe the answer is:
luge
'sport' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Maybe there's a link between them I don't understand?
'gun republican avoids' is the wordplay.
'gun' becomes 'luger' (type of pistol).
'republican' becomes 'R' (political abbreviation).
'avoids' is a deletion indicator.
'luger' with 'r' taken away is 'LUGE'.
Can you help me to learn more?
(Other definitions for luge that I've seen before include "Small sledge for one" , "Form of transport" , "Glue for a one-man sledge" , "Glue (anag) - racing toboggan" , "Small sleigh" .)
