Februari is kort.

Yes. In Dutch, the names of months are normally written with a lowercase letter: januari, februari, maart.

In this sentence, Februari is capitalized only because it is the first word of the sentence. If it appeared in the middle of a sentence, you would usually write februari.

Example:

• Februari is kort.
• In februari is het vaak koud.

That is simply the Dutch spelling of the month name. Many month names look similar to English, but not always identical.

For example:

• January → januari
• February → februari
• March → maart

So februari is just the normal Dutch form.

A common pronunciation is approximately fay-broo-AH-ree.

In IPA, it is often written roughly as /feː.bryˈaː.ri/.

A few things to notice:

• the r is Dutch, so it may sound different from an English r
• the stress is on -a-: fe-bru-A-ri
• Dutch vowels are usually clearer and less reduced than in English

Month names usually do not take an article in Dutch when you are simply naming the month.

So:

• Februari is kort.
• Maart komt na februari.

This is similar to English, where you also usually say February is short, not the February is short.

Is is the third-person singular present tense of the verb zijn, which means to be.

So:

• ik ben = I am
• jij bent = you are
• hij/zij/het is = he/she/it is

In Februari is kort, is links the subject Februari to the description kort.

Kort is an adjective. It describes Februari.

In this sentence it comes after the verb is, so it is being used predicatively.

Compare:

• Februari is kort. → predicative adjective
• een korte maand → attributive adjective before a noun

Because adjectives in Dutch usually do not take -e when they come after a linking verb like zijn.

So you say:

• Februari is kort.
• De maand is kort.

But before a noun, you often do add -e:

• een korte maand
• de korte maand

This is a very common Dutch pattern.

No, this is the basic Dutch sentence pattern:

subject + verb + complement

So:

• Februari = subject
• is = verb
• kort = complement/adjective

This is the same kind of structure as:

• Het huis is groot.
• De film is interessant.

Yes, absolutely. That is a very natural sentence.

• Februari is kort. = shorter, more direct
• Februari is een korte maand. = a little more explicit

Both are correct. The version without een maand is perfectly normal because the listener already understands what kind of thing February is.

Not necessarily. Kort can refer to length in several senses, including time.

Here it means that February has a short duration compared with other months. So it is about time/length, not physical height or size.

Dutch uses kort in a broad way, much like English short:

• een korte film = a short film
• een korte dag = a short day
• een korte maand = a short month

Not in normal standard writing, because it is the first word of the sentence, and the first word of a sentence is capitalized.

So the standard form is:

• Februari is kort.

But if the word is not at the start, then lowercase is correct:

• Ik vind februari kort.

Yes. It is short, correct, and natural.

A native speaker might also say:

• Februari is een korte maand.
• Februari duurt niet lang.

But Februari is kort is completely grammatical and idiomatic.
