Confuse A&E maybe, with obscure case of pinkeye (7)
I believe the answer is:
mistype
'confuse ae' is the definition.
I can't judge whether this defines the answer.
'with obscure case of pinkeye' is the wordplay.
'with' is a charade indicator (letters next to each other).
'obscure' becomes 'misty' (I've seen this in another clue).
'case of' says to hollow out the word (remove centre letters) (like emptying a case).
'pinkeye' with its centre taken out is 'pe'.
'misty' put next to 'pe' is 'MISTYPE'.
'maybe' is the link.
Can you help me to learn more?
(Other definitions for mistype that I've seen before include "Make an error in transcription" , "Use the wrong keyboard keys" , "Write incorrectly (on a keyboard)" , "Select wrong character" , "What poor secretary may do" .)
