Set day translated as settled date (6)
I believe the answer is:
steady
'settled date' is the definition.
'steady' can be an answer for 'date' (I've seen this before). I'm not sure about the 'settled' bit.
'set day translated' is the wordplay.
'translated' indicates an anagram.
'set'+'day'='setday'
'setday' anagrammed gives 'STEADY'.
'as' is the link.
Can you help me to learn more?
(Other definitions for steady that I've seen before include "Sensible, reliable" , "date seen regularly" , "Not wobbly" , "Firmly balanced, not rocking" , "Stable or regular" .)
