One disposed to help a learner at the piano? (3)
I believe the answer is:
pal
'one disposed' is the definition.
I can't tell whether this definition defines the answer.
'a learner at the piano?' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'at' says to put letters next to each other (I've seen this in other clues).
'the piano?' becomes 'p' (musical abbreviation).
'a'+'l'='al'
'al' after 'p' is 'PAL'.
'to help' acts as a link.
Can you help me to learn more?
(Other definitions for pal that I've seen before include "Mate, informal friend" , "Buddy, chum" , "China" , "Friend (colloq.)" , "Crony" .)
