Japanese verbal form te-aru

The verbal form te-aru catches many students by surprise. At first glance, it looks like just another grammar pattern, but in use it carries a very specific and subtle meaning. Most languages have no dedicated form for it, so the meaning has to be read from context.

The logic behind it is simple: te-aru describes an action that was done on purpose and whose result is still present. What matters is the state that the action produced. The construction is so common in everyday Japanese that it usually goes unnoticed.

What is the verbal form te-aru?

The form te-aru is built from the main verb in the te form followed by the verb ある (aru), which indicates the existence of something inanimate. Together they describe the result of an action that someone carried out intentionally.

One example makes it clear:

• ドアが開けてある (Doa ga akete aru) → The door is open (someone opened it on purpose and left it that way).

The sentence describes the state of the door and the intention behind it. Compare it with ドアが開いている (Doa ga aite iru), which only reports that the door is open, with no reference to who opened it.

Because someone must have acted, te-aru only attaches to transitive verbs, the ones that take an object, such as 開ける (akeru, to open), 置く (oku, to place) or 書く (kaku, to write). The person who acted usually remains unmentioned.

The affected thing is marked with が when the state is in focus, as in ドアが開けてある, or with を when the speaker stresses their own action, as in ドアを開けてある (Doa o akete aru). The article on the particles wa and ga with Japanese verbs explains this choice in more detail.

Particles

Now, let's familiarize ourselves with the particles that will arise during the lesson.

• の: It connects two elements, often translated as of or from. Example: 彼のノート (Kare no nōto): his notebook.
• を: It marks the object that receives the action of the verb; the object always comes right before this particle. Example: テレビを見る (Terebi o miru): to watch television.

Te Form

Before continuing, we need to know the te form.

To build the te form, you usually remove part of the verb and add て (te). Example:

• 見る → 見て (miru → mite): to see, to watch
• 食べる → 食べて (taberu → tabete): to eat

In both cases the る is dropped and て takes its place. Other verb groups form the te form differently, for example 書く → 書いて (kaku → kaite). The full explanation, with all the rules, is in the article on how the te form works in Japanese.

Teiru

When you want to say that an action is happening right now and continues, you use the teiru form.

Take the following sentence: 半分のケーキを食べている (Hanbun no kēki o tabeteiru). It means: half of the cake is being eaten.

To put the action in the past, you can use the た or ていた form.

• 半分のケーキを食べた (Hanbun no kēki o tabeta): I ate half of the cake.
• 半分のケーキを食べていた (Hanbun no kēki o tabeteita): I was eating half of the cake.

The difference is that the た form only says that the action is over, while ていた shows it was in progress at that moment. That progressive sense is useful to show that actions were happening together, for example:

• テレビを見てて、ケーキを食べていた (Terebi o mitete, kēki o tabeteita): I was watching television while eating cake.

Te aru

In てある, what stands out is the permanence of an action's result: the action is performed and its effect continues even long after it happened.

For example:

• 半分のケーキを食べてある (Hanbun no kēki o tabete aru): half of the cake has been eaten, and that remains true. The half that was eaten no longer exists, and this fact will not change.
  
• 顔に「嘘」って書いてあるよ (Kao ni “uso” tte kaite aru yo): “lie” is written on your face, and it stays written.
  
• 米は倉庫に貯蔵してある (Kome wa sōko ni chōzō shite aru): the rice is stored in the warehouse and remains there.
  
• 狭い空間に物がたくさん置いてあるね (Semai kūkan ni mono ga takusan oite aru ne): there are quite a few things in a small space, and they are still there taking up the space.
  
• アドレスは名刺に書いてある (Adoresu wa meishi ni kaite aru): the address is on the business card, written there and left as is.

In every sentence, the result points back to someone who acted deliberately. It is worth comparing てある with ておく: ておく highlights a task done in advance, while てある shows the state left behind after that task. When the written content itself is in focus, as in 書いてある, the verb often appears after the quoting particle と or its casual form って, as in 顔に「嘘」って書いてある.

Aru

We have seen the te form; now what does the ある that follows it mean?

ある (aru) means to exist, to remain, to be located, to arise or to happen. It is often confused with いる (iru), which carries similar meanings. The difference is that いる is used for living beings, while ある is used for inanimate things.

Example:

彼女がいる

There is a girlfriend.
He has a girlfriend.

ビルがある

There is a building.

In everyday Japanese, てある shows up on signs, in short notes, in prepared documents and whenever someone deliberately leaves something in place. As a rule of thumb: transitive verb, conscious action, lasting state. Once you start looking for those three elements, the form becomes easy to spot.
