Acme Co working to introduce new construction project (7)
I believe the answer is:
meccano
'construction project' is the definition.
The definition suggests a singular noun which matches the answer.
'acme co working to introduce new' is the wordplay.
'working' indicates anagramming the letters.
'to introduce' is an insertion indicator (to introduce to can mean to insert or include).
'new' becomes 'n'.
'acme'+'co'='acmeco'
'acmeco' is an anagram of 'meccao'.
'meccao' placed around 'n' is 'MECCANO'.
Can you help me to learn more?
(Other definitions for meccano that I've seen before include "Metal model construction set" , "Plaything" , "Children's nuts and bolts kit" , "Material to construct" , "It's for kids' building" .)
