Articles separately encountered during substantial part of weekend (8)
I believe the answer is:
saturday
'part of weekend' is the definition.
('Saturday' is part of 'weekend')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for saturday that I've seen before include "Samedi or Sabato or Samstag" , "It's Samedi in France" , "Part of the weekend" , "Day named for the sixth plant from the sun" , "- Night Fever, 1977 film" .)
