Thanks Amelia heartily, engaging in goodness without being savage (6)
I believe the answer is:
tamely
'without being savage' is the definition.
I can't judge whether this defines the answer.
'thanks amelia heartily engaging in goodness' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'heartily' says to take the centre (the inside or heart of the word).
'engaging in' means one lot of letters goes inside another (I've seen this in other clues).
'goodness' becomes 'my' (both are exclamations of surprise).
The central letters of 'amelia' are 'el'.
'el' placed within 'my' is 'mely'.
'ta'+'mely'='TAMELY'
Can you help me to learn more?
(Another definition for tamely that I've seen is " showing no spirit".)
