यह स्पीड पोस्ट है।

यह means this. It is used for something near the speaker, so यह स्पीड पोस्ट है। means This is speed post or This is a speed post item, depending on context.

It is singular. The usual contrasting word is वह, which means that.

The traditional pronunciation is close to yah, but in everyday modern Hindi many speakers say something closer to yeh.

So this sentence is often said as yeh speed post hai in natural speech.

A learner should also know that यह can sound very similar to ये in conversation, but in standard writing यह is singular and ये is plural or respectful.

Hindi normally does not use articles like a, an, and the the way English does.

So यह स्पीड पोस्ट है is completely normal without any extra word.

If you want to emphasize one or make the classification a little more explicit, you can say यह एक स्पीड पोस्ट है। But in many situations, एक is unnecessary.

है is the singular present-tense form of the verb to be. Here it means is.

So the basic pattern is:

यह = this
स्पीड पोस्ट = speed post
है = is

In plural or respectful speech, Hindi usually uses हैं instead of है.

Hindi usually puts the verb near the end of the sentence. That is one of the most basic word-order differences from English.

So English says:

This is speed post

but Hindi says, more literally:

This speed post is

That final-verb pattern is very common in Hindi.

Hindi uses many English loanwords, especially for modern services, offices, technology, and administration. स्पीड पोस्ट is a common borrowed expression, especially in Indian postal contexts.

Instead of translating the words into older or less common Hindi vocabulary, speakers often just use the English term and write it in Devanagari script:

स्पीड पोस्ट

This is completely normal Hindi usage.

In this sentence, gender does not really matter.

That is because है is used for both masculine and feminine singular, so the sentence looks the same either way.

With some borrowed nouns, gender can become clear only when you add adjectives or past-tense agreement. For a beginner, the important thing here is that यह स्पीड पोस्ट है। is correct and natural as it stands.

। is called the danda. It is the traditional Hindi full stop.

So यह स्पीड पोस्ट है। ends with the Hindi equivalent of a period.

In modern informal writing, especially online, people may also use a regular ., but । is standard and very common in textbooks and formal Hindi.
