Stray, being unreliable and a sexy type (5)
I believe the answer is:
satyr
'a sexy type' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'stray being unreliable' is the wordplay.
'being unreliable' is an anagram indicator (an unreliable or inaccurate spelling).
'stray' is an anagram of 'SATYR'.
'and' is the link.
Can you help me to learn more?
(Other definitions for satyr that I've seen before include "Horse man attending Bacchus" , "Chaser of wine and women" , "Woodland spirit" , "Lustful woodland god -- stray (anag)" , "lecher" .)
