Learn Turkish: Ocak ve şubat kış aylarıdır. - January and February are winter months.

In Turkish, months and days of the week are only capitalized when they are part of a specific date (like 5 Şubat). Here, Ocak is only capitalized because it is the first word of the sentence.

Why is there an -ı before the -dır in aylarıdır?

You need the -ı because kış ayları forms a noun compound meaning "winter months". When you combine two nouns like this in Turkish to make a new concept, the second noun gets a possessive suffix (here, -ı). It is literally "winter its-months".

Can you break down the exact parts of the word aylarıdır?

Sure! It is made of ay (month) + -lar (plural marker) + -ı (compound suffix linking it to kış) + -dır (the "to be" suffix meaning "are").

What is the purpose of the -dır suffix at the end of the sentence?

The -dır suffix acts like "is" or "are" here. It is used to state objective, general facts or encyclopedic knowledge. In everyday casual speech, you might hear people drop it and just say Ocak ve şubat kış ayları, but adding it makes the fact sound official.
