Rests, said to be a bit lazy (4)
I believe the answer is:
lays
'rests' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'said to be a bit lazy' is the wordplay.
'said' becomes 'ays' (I can't justify this - if you can you should give a lot more credence to this answer).
'to' says to put letters next to each other (I've seen this in other clues).
'be a bit' says to take the initial letters (I've seen 'a bit of' mean this).
The initial letter of 'lazy' is 'l'.
'ays' put after 'l' is 'LAYS'.
Can you help me to learn more?
(Other definitions for lays that I've seen before include "Arranges" , "literary works?" , "Puts down - narrative poetry" , "Puts down the old ballads" , "Minstrel's melodies" .)
