Rash oaths very out of place (9)
I believe the answer is:
overhasty
'rash' is the definition.
(I've seen this before)
'oaths very out of place' is the wordplay.
'out of place' indicates anagramming the letters.
'oaths'+'very'='oathsvery'
'oathsvery' is an anagram of 'OVERHASTY'.
(Other definitions for overhasty that I've seen before include "Too quick" , "not looking before leaping" , "too impulsive" , "Too hurried" , "Rash; too fast" .)
