Talks wildly of some strange disorder (5)
I believe the answer is:
rants
'talks wildly' is the definition.
(I've seen this in another clue)
'some strange disorder' is the wordplay.
'some' means to look at the middle letters.
'disorder' becomes 'ts' (I can't justify this - if you can you should give a lot more credence to this answer).
The middle letters of 'strange' are 'ran'.
'ran'+'ts'='RANTS'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for rants that I've seen before include "Loud pompous declamations" , "Raves" , "Noisily declaims" , "Loud bombastic declamations" .)
