4-30. The sort of the preposition : in (2), out, except

This video keeps introducing the preposition ‘in’ applied in a clause that the intransitive verb describes the subject.
The introduction about the preposition ‘is’ is continued from the previous video.
Please refer to the previous video to understand the entire context.
Then, the prepositions ‘out’ and ’except’-seemingly conveying similar definitions-are introduced to clarify the different premises on which the speaker applies either preposition in a clause.
Thank you for watching. ^^
