Seem willing to raise some donations (3)
I believe the answer is:
nod
'seem' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how one could define the other.
'willing to raise some donations' is the wordplay.
'willing' becomes 'on' (I've seen this in other clues).
'to raise' is a reversal indicator (in a down clue, letters go up).
'some' indicates taking the first letters.
The initial letter of 'donations' is 'd'.
'on' back-to-front is 'no'.
'no'+'d'='NOD'
Can you help me to learn more?
(Other definitions for nod that I've seen before include "Affirmative action?" , "Land of exile" , "OT land" , "Bob the head" , "positive sign" .)
