Semi-human creature Greek character encountered in youth (8)
I believe the answer is:
minotaur
'youth' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'semi-human creature greek character encountered in' is the wordplay.
'semi human creature' becomes 'minor' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'greek character' becomes 'tau' (letter from the Greek alphabet).
'encountered in' means one lot of letters goes inside another.
'minor' enclosing 'tau' is 'MINOTAUR'.
Can you help me to learn more?
(Other definitions for minotaur that I've seen before include "awful beast" , "Am in rout of a fabulous monster" , "Bull-headed type" , "Mythical creature" , "Creature, half-man and half-bull, slain by Theseus in the Cretan maze" .)
