Two French articles about Charlie, Dad's brother (5)
I believe the answer is:
uncle
'dad's brother' is the definition.
(I've seen this before)
'two french articles about charlie' is the wordplay.
I cannot really understand how this works, but
'about' could be 'c' (circa) and 'c' is located in the answer.
'french articles' could be 'unle' ('un' and 'le' are articles in French) and 'unle' is present in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for uncle that I've seen before include "He's related" , "Family relation" , "Grandfather's son" , "takes the pledge" , "Sam, perhaps" .)
