Floating Delta ice is likely to break (8)
I believe the answer is:
delicate
'likely to break' is the definition.
I can't tell whether this definition defines the answer.
'floating delta ice' is the wordplay.
'floating' indicates anagramming the letters (float can mean fluctuate or oscillate).
'delta'+'ice'='deltaice'
'deltaice' anagrammed gives 'DELICATE'.
'is' is the link.
Can you help me to learn more?
(Other definitions for delicate that I've seen before include "Very fine; fragile" , "Exquisitely fine, easily damaged" , "Flimsy" , "Exquisite; needing tactful handling" , "Fragile, fine-textured" .)
