Day in lagoon floating about in this? (7)
I believe the answer is:
gondola
'in this?' is the definition.
The definition suggests a singular noun which matches the answer.
'day in lagoon floating' is the wordplay.
'day' becomes 'd' (abbreviation for day).
'in' is an insertion indicator.
'floating' is an anagram indicator (float can mean fluctuate or oscillate).
'lagoon' anagrammed gives 'gonola'.
'd' put inside 'gonola' is 'GONDOLA'.
'about' acts as a link.
Can you help me to learn more?
(Other definitions for gondola that I've seen before include "Venice craft" , "Supermarket display unit" , "Venetian vessel" , "Compartment suspended from an airship" , "Traditionally used on Venetian canals" .)
