And teases about the streamers (7)
I believe the answer is:
ribands
'streamers' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'and teases about' is the wordplay.
'teases' becomes 'ribs' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'and' placed inside 'ribs' is 'RIBANDS'.
'the' acts as a link.
Can you help me to learn more?
(Another definition for ribands that I've seen is " Blue cloth bands as trophies".)
