Learn Finnish: Tämä kahvi on entistä aromikkaampaa ja täyteläisempää. - This coffee is more aromatic and more full-bodied than before.

Entistä is the partitive form of the adjective entinen (former, previous). In Finnish, you can express "more than X" by putting X in the partitive case directly before the comparative adjective. So, entistä aromikkaampaa literally translates to "more aromatic than the former". It is a very common and elegant structure used to say "more [adjective] than before."

Could I just say aromikkaampaa kuin ennen instead?

Yes, absolutely! Tämä kahvi on aromikkaampaa kuin ennen is perfectly correct and means exactly the same thing. However, using entistä + comparative is highly natural in Finnish and is often preferred in slightly more descriptive or formal contexts, such as food packaging, reviews, or advertising.

Why are the comparative adjectives aromikkaampaa and täyteläisempää in the partitive case instead of the basic nominative form?

They are in the partitive because the subject, kahvi (coffee), is an uncountable mass noun. When describing a mass noun acting as a substance with the verb olla (to be), the describing adjective must be in the partitive case. So "The coffee is aromatic" is Kahvi on aromikasta, and "The coffee is more aromatic" becomes Kahvi on aromikkaampaa.

What is the base form of aromikkaampaa, and how does it change into this form?
