Hugo is out of yoghourts or is that a lie? (5)
I believe the answer is:
story
'a lie?' is the definition.
(story is a kind of lie)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for story that I've seen before include "Narration" , "See 10 and 19" , "Rumour" , "Narrative or account" , "Tale - lie" .)
