Rare earth? Try it out with some hesitation (7)
I believe the answer is:
yttrium
'rare earth?' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'try it out with some hesitation' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'with' is a charade indicator (letters next to each other).
'some hesitation' becomes 'um' (um is said in hesitation).
'try'+'it'='tryit'
'tryit' with letters rearranged gives 'yttri'.
'yttri'+'um'='YTTRIUM'
Can you help me to learn more?
(Other definitions for yttrium that I've seen before include "Rare earth element" , "Chemical element; um, try it (anag.)" , "Metallic element, symbol Y" , "Silvery metallic element" , "Table item" .)
