~つつある— In the Process of Changing
Attaches to a verb stem to express that an action or change is steadily and continuously progressing toward completion. It captures a gradual shift over time (recovering, increasing, disappearing) and feels more formal and written than the everyday ~ている. Used mainly for changes in state, not one-off actions.

Commonly confused with
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~つつある is tested against.
vs~ている
~ている simply states an action is ongoing; ~つつある stresses a gradual movement toward completion and is more formal.
vs~つつ(も)
~つつ(も) means 'while / even though' (two simultaneous actions or concession); ~つつある means 'is in the process of changing'.
