Learn Turkish: Kurumsal kültür gelişmektedir. - Corporate culture is developing.

Kurumsal comes from the noun kurum (institution or corporation) plus the relational adjective suffix -sal. This suffix turns nouns into adjectives meaning pertaining to or related to that noun. Here, it transforms the noun institution into the adjective institutional or corporate.

Could kurumsal refer to non-business entities as well?

Yes! Because the root word kurum simply means institution or organization, kurumsal translates to institutional just as often as corporate. You can use it to describe the culture of a university, a government agency, or a non-profit, not just a business.

Why does this sentence use gelişmektedir instead of the more familiar gelişiyor?

The -mekte (or -makta) suffix is a formal, written equivalent of the present continuous -yor. You will frequently see it in news articles, business reports, and academic writing. While gelişmekte means exactly the same thing as gelişiyor (is developing), it fits the professional tone of discussing corporate culture much better.

What does the -dir at the end of gelişmektedir do?
