I disagree. As the other comments have stated, umami and savory are completely different words. I agree that kawaii and cute are synonyms, but I only see it being used in vaguely japanese-related contexts, where it's not necessary but also not in any way a misuse, similar to how "hors d'oeuvre" is used in place of "appetizer".

People using "umami" in English is a big pet peeve of mine. It's so damn pretentious. "Savory" covers the meaning more than adequately and has existed in the language for a long time. There's no reason for the foreign loan word except to try to sound super smart.

Umami refers to a specific flavour, savoury refers to a broad category of foods that are basically not sweet. You can have "savoury" meals that have no umami flavour.

I can assure you that japanese people don't refer to umami as a flavor lol

Umami is a subset of savory.

It's not pretentious (when used correctly), it's more precise.

That is correct. I buy a liquid specifically labeled as ‘Umami’ that my family adds to vegetables, rice, etc.

Is the liquid MSG solution or is there something else in there?

No MSG.

So what is it?

Yondu vegetable umami

That seems to be made from fermented soybeans which is also how pure MSG is produced. I’m pretty sure the main active component of this is also just MSG, although they point out that they don’t explicitly add artificial MSG.

It’s not the same flavor

Can you not distinguish the flavour of umami from other flavors?

It's easy to find examples such as:

"Taste receptors in the mouth sense the five basic tastes: sweetness, sourness, saltiness, bitterness, and savoriness (also known as savory or umami)"
