"Awful creeps", one put in, "is absolutely right" (7)

I believe the answer is:
precise
'absolutely right' is the definition.
'precise' can be an answer for 'right' (similar in meaning). I am unsure of the 'absolutely' bit.
'awful creeps one put in' is the wordplay.
'awful' indicates anagramming the letters.
'one' becomes 'i' (Roman numeral).
'put in' indicates putting letters inside.
'creeps' anagrammed gives 'precse'.
'precse' placed around 'i' is 'PRECISE'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for precise that I've seen before include "Specific" , "'Exact, accurate (7)'" , "Recipes (anag.)" , "Exact like recipes" , "Highly accurate and sharply exact" .)
