Ongoing States in Japanese: Te Iru vs. Te Aru

Welcome to Chapter 11! You probably learned 〜ている (te iru) as the Japanese equivalent of "-ing" for actions in progress. While that's true, this versatile form has several other important uses that are crucial for sounding natural. We'll also look at a related pattern, 〜てある (te aru), which describes states resulting from intentional actions.

The Three Main Uses of 〜ている (te iru)

1. Ongoing Action (Present Progressive)

This is the first meaning you learned: an action happening right now.

雨が降っています。(Ame ga futte imasu.)

It is raining.

2. Resulting State

This is a very common but tricky usage. For verbs that describe an instantaneous change (like getting married, dying, or getting to know something), the ている form describes the state that results from that action.

田中さんは結婚しています。(Tanaka-san wa kekkon shite imasu.)

Mr. Tanaka is married. (NOT "is getting married")

私は大阪に住んでいます。(Watashi wa Ōsaka ni sunde imasu.)

I live in Osaka. (The state resulting from the act of moving in)

3. Habitual or Repeated Actions

〜ている can also describe actions that you do regularly, like a job or a hobby.

私は日本語を教えています。(Watashi wa nihongo o oshiete imasu.)

I teach Japanese (as a profession).

〜てある (te aru) - Result of an Intentional Action

This pattern is used to describe a state that exists because someone put it in that state for a specific purpose or reason. The focus is on the resulting state of the object, not on who performed the action.

Key Features of 〜てある

It is only used with transitive verbs.
The object is marked with が (ga), not を (o).
It implies the action was done intentionally and in preparation for something.

Let's compare:

ドアが開いています。 (Doa ga aite imasu.)	The door is open. (A simple observation of its state. Uses intransitive verb 開く).
ドアが開けてあります。 (Doa ga akete arimasu.)	The door has been opened. (Implying someone opened it for a reason, like letting guests in. Uses transitive verb 開ける).
