I’ve it, rate variation can be done over and over again (9)
I believe the answer is:
iterative
'done over and over again' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can sometimes define each other.
'i've it rate variation' is the wordplay.
'variation' is an anagram indicator.
'ive'+'it'+'rate'='iveitrate'
'iveitrate' is an anagram of 'ITERATIVE'.
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for iterative that I've seen before include "bears repeating" , "Relating to repetition" , "Involving repetition" , "repeated" .)
