Is the speaker on type of TV friendly? (8)
I believe the answer is:
amicable
'friendly?' is the definition.
('amicable' is associated in meaning with 'friendly')
'is the speaker on type of tv' is the wordplay.
'is the speaker' becomes 'am I' (the person speaking asking 'am I...?').
'on' says to put letters next to each other.
'type of tv' becomes 'cable' (cable TV is a type of TV).
'ami'+'cable'='AMICABLE'
(Other definitions for amicable that I've seen before include "Friendly, reasonable" , "Friendly, peaceable" , "Of friendly and affable disposition" , "Easy to approach" , "In friendly spirit" .)
