Understanding Prepositions of Time

This video tutorial by Andrew at Crown Academy of English covers the grammar topic of prepositions of time, focusing on 'by' and 'until'. 'By' is used to indicate a deadline or a time limit, meaning something must happen before a specific time. 'Until' describes a continuous action that stops at a specific time. The video also highlights common mistakes made by non-native speakers, such as using 'until' with numbers, where 'up to' should be used instead. The lesson concludes with a quiz to reinforce the differences between 'by' and 'until'.
