In biology, being in a condition of suspended animation (6)
I believe the answer is:
torpid
'suspended animation' is the definition.
'torpid' can be an answer for 'suspended' (thesaurus). I'm not certain of the 'animation' bit.
'in biology being in a condition of' is the wordplay.
I cannot quite see how this works, but
'being' could be 'pi' (PI is an example) and 'pi' is found within the answer.
'of' could be 'o' and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for torpid that I've seen before include "Inactive, dormant" , "Sluggish and inactive" , "Inert" , "Lethargic, sluggish" , "Lethargic - drop it (anag)" .)
