～ている ①Estar ~iendo, Estar ~ando

The Verb + て form is used to connect a verb to another verb, or another part of the sentence. When combined with いる, it describes an ongoing action or state. For example, 食べている means 'I am eating,' and 死んでいる means 'I am dead.' Whether ている conveys an action (like 'is -ing') or a state depends on the verb. In casual speech, ている is often shortened to てる.

The ている① form describes an ongoing action or state. ているところだ conveys the same meaning but emphasizes being 'right in the middle' of doing something. For example, 食べている means 'I am eating,' while 食べているところだ emphasizes 'I'm in the middle of eating,' which could explain why you can't talk long on the phone, for example.

The ている① form describes an ongoing action or state. When combined with あいだに (meaning 'while doing something'), it expresses the idea of 'while doing A, B happened.' This is typically used for events outside the speaker's control. For example, 映画を見ている間に、電話が掛かってきました means 'While I was watching a movie, a phone call came in.'

The ている form describes an ongoing action or state. With verbs that describe actions over time, it functions like the English 'is...-ing,' but with state verbs, it means to be (or continue to be) in that state. For example, 食べている means 'is/am eating,' while 死んでいる means 'is/are dead' (not 'is dying').

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 is a common structure in Japanese to express an ongoing action or state. つづける attached to the verb stem expresses a similar meaning, but with a greater emphasis on the idea of continuation. For example, 増えている means that something is increasing or has increased, while 増えつづけている carries the additional nuance that it is continuing to increase.

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, 読んでいる本 means 'the book [I] am reading.' However, when describing a noun's state, the past form (た) 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.
