Immediately, I see something that makes communications difficult (6)
I believe the answer is:
static
'something that makes communications difficult' is the definition.
I can't judge whether this defines the answer.
'immediately i see' is the wordplay.
'immediately' becomes 'stat' (stat can informally mean at once).
'see' becomes 'C' (the word for the letter, according to Chambers).
'stat'+'i'+'c'='STATIC'
Can you help me to learn more?
(Other definitions for static that I've seen before include "Lacking movement or action" , "Crackling or hissing noise caused by electrical interference" , "Steady" , "fixed" , "Motionless like some kind of electricity" .)
