Very encouraging to see home piano trials arranged (13)
I believe the answer is:
inspirational
'very encouraging' is the definition.
'inspirational' can be an answer for 'encouraging' (I've seen this before). I am not sure about the 'very' bit.
'home piano trials arranged' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'arranged' indicates anagramming the letters (letters rearranged).
'piano'+'trials'='pianotrials'
'pianotrials' with letters rearranged gives 'spirational'.
'in'+'spirational'='INSPIRATIONAL'
'to see' is the link.
Can you help me to learn more?
(Other definitions for inspirational that I've seen before include "Tending to stimulate the mind" , "stirring" , "Heartening, motivating" , "Generating an elevated feeling" , "(Of idea) touched with genius" .)
