Repetitive noise from rodent let loose (6)
I believe the answer is:
rattle
'repetitive noise' is the definition.
'rattle' can be an answer for 'noise' (thesaurus). I am unsure of the 'repetitive' bit.
'rodent let loose' is the wordplay.
'rodent' becomes 'rat' (rat is a kind of rodent).
'loose' indicates an anagram (letters are loosened from their original positions).
'let' anagrammed gives 'tle'.
'rat'+'tle'='RATTLE'
'from' is the link.
Can you help me to learn more?
(Other definitions for rattle that I've seen before include "Toy for baby or football fan" , "Baby's toy - conductor" , "Baby's toy; irritate" , "Vibrate noisily" , "Make worried, baby's toy" .)
