Some splendid act I cited teaching a lesson (8)
I believe the answer is:
didactic
'teaching a lesson' is the definition.
'didactic' can be an answer for 'teaching' (I've seen this before). I'm not certain of the 'a lesson' bit.
'some splendid act i cited' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'DIDACTIC' can be found hidden inside 'splendid act i cited'.
Can you help me to learn more?
(Other definitions for didactic that I've seen before include "Intended to teach or instruct" , "like a school-teacher?" , "(Patronisingly) educational" , "Like a teacher" , "Edifying" .)
