In a cheap example, it's high (4)
I believe the answer is:
apex
'high' is the definition.
(thesaurus)
'in a cheap example it's' is the wordplay.
'in' says the answer is hidden in the clue.
'APEX' is hidden within 'cheap example its'.
(Other definitions for apex that I've seen before include "high-point" , "Point or summit" , "Summit - pinnacle" , "Absolute peak" , "Top point" .)
