Highly praise guile so easily at start — out of order! (8)
I believe the answer is:
eulogise
'highly praise' is the definition.
'eulogise' can be an answer for 'praise' (eulogising is a kind of praising). I'm not sure about the 'highly' bit.
'guile so easily at start out of order' is the wordplay.
'at start' says to take the initial letters.
'out of order' indicates an anagram.
The initial letter of 'easily' is 'e'.
'guile'+'so'+'e'='guilesoe'
'guilesoe' is an anagram of 'EULOGISE'.
Can you help me to learn more?
(Other definitions for eulogise that I've seen before include "Acclaim" , "Speak in praise of person" , "Praise formally and eloquently" , "Laud" , "Praise highly" .)
