Chair perplexed by speaker (6)
I believe the answer is:
throne
'chair perplexed by speaker' is the definition.
'throne' can be an answer for 'chair' (I have seen 'Chair of state' mean 'throne' so perhaps 'chair' could also mean 'throne'). I'm not certain of the 'perplexed by speaker' bit.
'by speaker' is the wordplay.
'by' becomes 'thro' (I've seen this in other clues).
'speaker' becomes 'ne' (I can't explain this - if you can you should give a lot more credence to this answer).
'thro'+'ne'='THRONE'
Can you help me to learn more?
(Other definitions for throne that I've seen before include "heads" , "Royalty sits on it" , "Bishop's chair" , "toilet" , "Seat of royal power" .)
