Insincere, like Wensleydale? (6)
I believe the answer is:
cheesy
'insincere' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'like wensleydale?' is the wordplay.
I cannot quite see how this works, but
'like' could be 'y' (similar in meaning) and 'y' is located in the answer.
The remaining letters 'chees' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cheesy that I've seen before include "Hackneyed, trite" , "Lancashire so" , "Inferior" , "showing poor taste" , "Sentimental (like camembert?)" .)
