Both grammar structures mean “to be doing…”.


つつある tsutsuaru

つつある is used with Vます(remove ます)

This structure expresses the meaning “to be in the middle of a transformation”. It does not indicate the progress of action.

Example :

Chichi no byouki ha dandan naori tsutsuaru.
My father’s illness is gradually getting better.

Daigakusei no toki no kinen ha wasure tsutsu aru.
I’m forgetting memories of my student days.

Sofu ha toshi wo toru to, karada ga yowaku nari tsutsu aru.
My grandfather is getting weaker as he gets older.

ている teiru

ている means “The result of the state after an action / event occurs”

When verbs going with ている are verbs indicating the action, this structure expresses the meaning “in the middle of the action/event”.

Example :

Nihon no seikatsu ni narete imasu.
I am used to living in Japan. (The speaker is used to living in Japan – this is the result).

Watashi no kuni no dentou bunka ga kiete imasu.
The traditional culture of my country is disappearing.

A : “Eiga ga hajimatte imasu yo.”
B : “Sou ka.”
A : “The movie is starting.”
B : “Really?”

Note : When changing from [Vつつある] to [Vている], the meaning is changed a lot. When changing to「てきている」, the meaning is not changed.

Example :

Ano machi ha toshika shi tsutsu aru.
This town is urbanizing (The urbanization is happening).

Ano machi ha toshika shite iru.
That town is urbanized (The urbanization happened – urbanization is the result).

Ano machi ha toshika shitekite iru.
