Feathered hat it’s surprising king wears like that (5)
I believe the answer is:
shako
'feathered hat' is the definition.
'shako' can be an answer for 'hat' (shako is a kind of hat). I am unsure of the 'feathered' bit.
'surprising king wears like that' is the wordplay.
'surprising' becomes 'ha' (I can't explain this - if you can you should believe this answer much more).
'king' becomes 'K' (chess abbreviation).
'wears' is an insertion indicator.
'like that' becomes 'so' (as in 'like so').
'ha'+'k'='hak'
'hak' put within 'so' is 'SHAKO'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for shako that I've seen before include "Capital cover" , "Cylindrical military hat with peak and plume? Really has, ok" , "hat from soldier" , "Plumed military cap" , "One covering for military head" .)
