～ている ③Has/have done, Is ~ing (Repetition)

The Verb + て form connects verbs or parts of a sentence. One common use of this form is to connect it to the existence verb いる to express continuing or repeated actions, like going to work or going to sleep at the same time every day. Note that the specific nuance of ている can depend on the verb and context (see ている① and ている②).

The ている form describes an ongoing action or state. In the ている① form, it expresses something you are currently doing, like 食べている ('I am eating'). In the ている③ form, it refers to a habitual or repeated action, even if you're not currently doing said action, often paired with a time word. For example, 毎朝３０分走っている means 'I run every morning for 30 minutes.'

ている expresses an ongoing action or state. The ている② form is used with verbs indicating a single change in state, like 死んでいる ('is dead'), not an action. The ている③ form describes repeated or habitual actions, like 会社で働いている could mean ('I'm working for [that/this] company).

The ている① form expresses completed actions or past states. Unlike English, verbs can directly modify nouns, similar to い-Adjectives. For example, 行っている学校 means 'the school I am going to.' However, when describing a noun's state, the past form is often preferred over ている. For example, 死んだネズミ ('a dead mouse') is more common than 死んでいるネズミ.
