Learn Turkish: Akıl ve sağlık önemli. - Mind and health are important.

In Turkish, the present tense "to be" verb (like "is" or "are") is often left out when stating a simple fact. The word önemli (important) by itself at the end of the sentence naturally implies "are important."

Since "mind and health" are two things, why doesn't önemli have a plural ending like önemliler?

In Turkish, when the subject is non-human (like mind and health), the verb or adjective at the end usually stays singular even if the subject is plural. You do not need to add the plural suffix -ler to önemli here.

What does the -li ending on önemli do?

The suffix -li means "with" or "having." It turns a noun into an adjective. Here, it attaches to the noun önem (importance) to make önemli, which literally means "with importance" or "important."

How is the word sağlık formed?

The suffix -lık is very common in Turkish for turning words into abstract nouns. Here, it attaches to sağ (which means alive, healthy, or sound) to create sağlık, meaning "health."
