A sequence of letters that often follows right after some unwelcome flirtatious overtures (6)
I believe the answer is:
suffix
'a sequence of letters that often follows' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'right after some unwelcome flirtatious overtures' is the wordplay.
'right' becomes 'fix' ().
'after' says to put letters next to each other.
'overtures' says to take the initial letters.
The first letters of 'some unwelcome flirtatious' is 'suf'.
'fix' put after 'suf' is 'SUFFIX'.
Can you help me to learn more?
(Other definitions for suffix that I've seen before include "Addition to end of word" , "Letter or letters added to the end to make another word" , "The 'ly' of 'badly'?" , "Append" , "-ing, e.g." .)
