Go soft and old, somehow (4)
I believe the answer is:
plod
'go' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'soft and old somehow' is the wordplay.
'soft' becomes 'p' (musical abbreviation for 'piano').
'and' says to put letters next to each other.
'somehow' is an anagram indicator.
'old' anagrammed gives 'lod'.
'p'+'lod'='PLOD'
Can you help me to learn more?
(Other definitions for plod that I've seen before include "Heavy walk; PC (slang)" , "bluebottle, say" , "Work (or walk) laboriously" , "Trudge - policeman" , "Noddy's police constable" .)
