Glue, perhaps, joining two animals? (7)
I believe the answer is:
sealant
'glue' is the definition.
The definition and answer can be both substances as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'joining two animals?' is the wordplay.
'two animals?' can mean two replacements for 'animal'.
'joining' means one lot of letters go next to another.
'animal' becomes 'seal' (I have seen 'Marine animal' mean 'seal' so perhaps 'animal' could also mean 'seal').
'animal' becomes 'ant'.
'seal' next to 'ant' is 'SEALANT'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for sealant that I've seen before include "Material stopping leaks" , "Material for plugging leaks" , "Material to prevent leakage" , "Substance for closing something tightly" , "Bond" .)
