Compound in which there are two animals (7)
I believe the answer is:
wolfram
'compound in which there' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Maybe there's an association between them I don't understand?
'two animals' is the wordplay.
'two animals' can mean two replacements for 'animal'.
'animal' becomes 'wolf' (I have seen 'Predatory animal' mean 'wolf' so perhaps 'animal' could also mean 'wolf').
'animal' becomes 'ram' (male sheep).
'wolf'+'ram'='WOLFRAM'
'are' acts as a link.
Can you help me to learn more?
(Other definitions for wolfram that I've seen before include "Tungsten" , "elemental" , "Element by another name" , "at no 74, originally" , "hard stuff" .)
