Copper fool about making cylindrical fungi sac? (5)
I believe the answer is:
ascus
'cylindrical fungi sac?' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'copper fool about' is the wordplay.
'copper' becomes 'cu' (chemical symbol).
'fool' becomes 'ass' (both can mean a stupid person).
'about' means one lot of letters goes inside another.
'cu' going inside 'ass' is 'ASCUS'.
'making' acts as a link.
Can you help me to learn more?
(Another definition for ascus that I've seen is " cell".)
