Inflammatory condition to pen in speech (4)
I believe the answer is:
stye
'inflammatory condition' is the definition.
'stye' can be an answer for 'condition' (stye is a kind of condition). I'm not certain of the 'inflammatory' bit.
'pen in speech' is the wordplay.
'pen' becomes 'sty' (both can mean an animal enclosure).
'in speech' shows a homophone (sound like).
'sty' sounds like 'STYE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for stye that I've seen before include "pain for the observer" , "Inflamed swelling on the edge of an eyelid" , "Ocular affliction" , "Ocular inflammation" , "producing eyesore" .)
