Record -- I seem disturbed by it (7)
I believe the answer is:
itemise
'record' is the definition.
('record'->'itemize' is in my internal thesaurus and 'ize'->'ise')
'i seem disturbed by it' is the wordplay.
'disturbed' indicates anagramming the letters.
'by' says to put letters next to each other.
'i'+'seem'='iseem'
'iseem' is an anagram of 'emise'.
'emise' after 'it' is 'ITEMISE'.
(Other definitions for itemise that I've seen before include "Read off list of things one by one" , "List exhaustively" , "List in detail" , "catalogue" , "Formulate a list" .)
