Notices sailors become dazzled (3,5)
I believe the answer is:
see stars
'dazzled' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'notices sailors' is the wordplay.
'notices' becomes 'sees' (to notice is to observe or see).
'sailors' becomes 'tars' (tar is a kind of sailor).
'sees'+'tars'='SEE STARS'
'become' is the link.
Can you help me to learn more?
(Other definitions for see stars that I've seen before include "Recognise celebrities" , "You may after whack on the head" , "Be stunned" , "affected by flashing lights" , "Look dazed" .)
