Occasionally, this journalist should get knotted! (4)
I believe the answer is:
tied
'knotted' is the definition.
(similar in meaning)
'occasionally this journalist' is the wordplay.
'occasionally' indicates alternate letters.
'journalist' becomes 'ed' (short for editor).
The alternate letters of 'this' are 'ti'.
'ti'+'ed'='TIED'
'should get' acts as a link.
(Other definitions for tied that I've seen before include "(Of pub) controlled by a brewery" , "In no-win situation" , "Drew; bound" , "United" , "limited" .)
