Light support from one breaking into wonderful cry of approval (9)
I believe the answer is:
girandole
'light support' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'one breaking into wonderful cry of approval' is the wordplay.
'one' becomes 'i' (Roman numeral).
'breaking into' means one lot of letters goes inside another.
'wonderful' becomes 'grand' (I've seen this in another clue).
'cry of approval' becomes 'ole' (Spanish exclamation of approval).
'i' inserted within 'grand' is 'girand'.
'girand'+'ole'='GIRANDOLE'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for girandole that I've seen before include "a number of mines linked together" , "firework" .)
