Being virginal, mistakenly chased? (6)
I believe the answer is:
chaste
'being virginal' is the definition.
(similar in meaning)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for chaste that I've seen before include "Morally pure" , "Sexually virtuous" , "Continent" , "Innocent" , "'Celibate, virginal (6)'" .)
