Intro / Sponsor

skip

The video opens with the speaker introducing themselves in Makassar, Indonesia, using 'in' for the city and 'on' for the street. A TikTok scrolling joke transitions into the lesson's purpose: clarifying preposition confusion.

  • Speaker uses personal examples to ground abstract grammar rules.
  • Humor engages viewers before technical content.

Intro is brief and non-instructional.

0:30-7:53

Time Prepositions

watch

The speaker breaks down 'in,' 'on,' and 'at' for time, using examples like 'in the future,' 'on February 27,' and 'at 5 AM.' They emphasize 'in' for broad periods (months, years), 'on' for dates/holidays, and 'at' for exact times. Exceptions like 'at Christmas' vs. 'on Christmas Day' are explained.

  • 'In' covers general time spans (months, seasons).
  • 'On' is for specific dates and holidays.
  • 'At' denotes precise moments (5 AM, midnight).

Core content with actionable rules.

7:53-15:02

Place Prepositions

watch

The speaker applies the same hierarchy to place: 'in' for countries/cities, 'on' for streets/surfaces, and 'at' for specific addresses. Examples include 'in Indonesia,' 'on Jalan Ahmad Yani,' and 'at Starbucks.' Nuances like 'in a car' vs. 'on a bus' are clarified.

  • 'In' applies to enclosed spaces (cars, classrooms).
  • 'On' describes surfaces (tables, floors).
  • 'At' specifies exact locations (homes, events).

Essential for mastering place-based prepositions.

15:02-15:21

Conclusion

optional

The speaker summarizes key rules and invites viewers to practice forming sentences. They thank the audience and tease the next video.

  • Repetition of rules aids retention.
  • Call-to-action encourages engagement.

Brief recap with no new information.

Key points

  • General vs. Specific Time Rules — Use 'in' for broad time periods (months, years, seasons), 'on' for specific dates/holidays, and 'at' for precise times (5 AM, midnight).
  • Place Hierarchy — Use 'in' for countries/cities, 'on' for streets/surfaces, and 'at' for specific addresses or locations (e.g., Starbucks).
  • Overlapping Exceptions — Some holidays (e.g., Christmas) can use 'on' or 'at' depending on context (e.g., 'at Christmas' vs. 'on Christmas Day').
In is more general, on is somewhat general but more specific, and at is very specific. Tc Idaa

7:53

prepositions of time Then how

7:57

to use in on and at as

8:02

pay attention one by one Okay the

8:04

interesting thing here is in on and at

8:07

as prepositions of place

8:09

use the same rules on

8:11

the use of in on and add as

8:14

prepositions of time so based on

8:18

the level

8:19

in for a very general place

8:23

then on is for a somewhat

8:27

general or more specific place compared to

8:29

in and at for a very

8:33

specific place okay the first in for the

8:37

country so if we talk about the

Jakarta do you live in Kuningan Jakarta

9:43

then in is used for

9:48

closed spaces and transportation where we

9:52

cannot stand or walk

9:55

in it so when we enter the

9:59

sit so we cannot stand or

10:01

walk like in a car in a taxi in a

newspaper Now on to

10:42

indicate a location or place that is rather

10:46

specific or eh rather general not

10:49

too general like in because in is the

10:52

scope broader in essence on is

10:56

a bit smaller in scope compared to in

11:00

first on is used for street names

12:45

very specific place the first is

12:48

used for an address Well earlier

12:52

if e on can be used for street names

12:56

but if add it already has a

12:59

house number for example at 78 Manuruki Street

13:04

Well so there is already a street name and

13:06

there is already a house number so it is

13:08

really very specific if

13:10

friends using add for the address is

13:12

really when friends

13:14

give their address other people will

13:16

understand Oh the house number That's all and the

13:19

street name here but if on it's

13:22

just the street name without the house number

13:25

okay it's different yeah Besides it's used

13:28

for specific locations like at
