Spiritual tenant lends car out (14)
I believe the answer is:
transcendental
'spiritual' is the definition.
(thesaurus)
'tenant lends car out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'tenant'+'lends'+'car'='tenantlendscar'
'tenantlendscar' with letters rearranged gives 'TRANSCENDENTAL'.
(Other definitions for transcendental that I've seen before include "Pi is" , "Relating to the spiritual realm" , "like a number of mathematicians?" , "Supereminent" , "'being in the spiritual realms' maybe" .)
