Nuisances for the viewers left out of formats (5)
I believe the answer is:
styes
'formats' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for styes that I've seen before include "Pig pens" , "Problems seeing" , "They make it difficult to see" , "Eyesores" , "gatherings" .)
