て-Form Rules (Overview)
The complete guide to て-form conjugation across verb groups.
The Swiss Army Knife of Verbs
Imagine you are in a Japanese cafe. You want to ask for the menu, tell a friend what you are doing, or ask for permission to sit down. You cannot just use the dictionary form of a verb for these tasks. You need a special 'bridge' form that connects your actions to other requests or states.
How to Conjugate
Verbs are categorized into three groups. Each group has a specific rule for changing the dictionary form into the て-form.
Tip
Examples in Action

Hint: The dictionary form is 飲む (nomu). It is a Group 1 verb ending in 'mu'.
Please drink water.
When to Use It
The te-form is not a sentence on its own; it always attaches to another auxiliary or verb.
