Derive satisfaction from renovated teak organ (4,5)
I believe the answer is:
take heart
'derive' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
'satisfaction from renovated teak organ' is the wordplay.
I cannot really understand how this works, but
an anagram of 'teak' is 'take' which is present in the answer.
'organ' could be 'heart' (the heart is an organ of the body) and 'heart' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for take heart that I've seen before include "Don't be discouraged - seek cardiac support (4,5)" , "Be encouraged or cheered up in cardiac way" , "how to gain courage" , "to leave outside leaves of lettuce" , "Have courage, acquire cardiac boost" .)
