Te-Form & Connecting Lesson 7
This lesson covers the essential functions of the Te-form, including state of being (ている/てある), granting permission (てもいい), and prohibition (てはいけない).
Navigating Daily Life
When you are in Japan, you often need to describe what is happening around you, ask for permission to do something, or understand rules in public spaces. The Te-form is the key to connecting these ideas.
Core Te-Form Structures
The Te-form is the 'glue' of Japanese grammar. It allows you to combine verbs with auxiliary verbs to express state, permission, and prohibition.
- ている: Describes an ongoing action or a state. 2. てある: Describes a state resulting from a deliberate action. 3. てもいい: Used to grant or ask for permission. 4. てはいけない: Used to express prohibition (must not).
