Come through and have a look at the piano (4)
I believe the answer is:
seep
'come through' 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?
'have a look at the piano' is the wordplay.
'have a look at' becomes 'see' (I've seen this in another clue).
'the piano' becomes 'p' (musical abbreviation).
'see'+'p'='SEEP'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for seep that I've seen before include "Leak slowly, ooze" , "Of liquid, ooze slowly out" , "Leak gradually" , "Ooze, percolate" , "Leak through an opening" .)
