התיכון ליד הפארק.

In Hebrew, the verb to be is usually left out in the present tense.

So:

• התיכון ליד הפארק. literally looks like: the high school next to the park but it means: The high school is next to the park.

This is very normal in Hebrew. Compare:

• הילד בבית. = The boy is at home.
• הספר על השולחן. = The book is on the table.

In past or future tense, Hebrew does use forms of to be:

• התיכון היה ליד הפארק. = The high school was next to the park.
• התיכון יהיה ליד הפארק. = The high school will be next to the park.

התיכון means the high school.

It is made of:

• תיכון = high school
• ה־ = the

So:

• תיכון = a high school / high school
• התיכון = the high school

In modern Hebrew, תיכון is a very common shorthand for בית ספר תיכון, which literally means secondary school / high school.

The prefix ה־ is the Hebrew definite article, meaning the.

So in this sentence:

• התיכון = the high school
• הפארק = the park

Unlike English, where the is a separate word, in Hebrew it is usually attached directly to the noun.

Examples:

• ספר = book

• הספר = the book

• פארק = park
• הפארק = the park

ליד is a preposition meaning next to, beside, or sometimes near, depending on context.

So:

• ליד הפארק = next to the park

Examples:

• הבית ליד הים. = The house is ליד the sea / next to the sea.
• אני יושב לידך. = I am sitting next to you.

It is a very common location word in Hebrew.

Because Hebrew still adds the definite article ה־ to loanwords and foreign-origin nouns.

So even though פארק comes from a foreign source, Hebrew treats it like a normal noun:

• פארק = park
• הפארק = the park

This happens with many modern words:

• טלפון = telephone

• הטלפון = the telephone

• אוטובוס = bus
• האוטובוס = the bus

It can function as a full sentence in Hebrew:

• התיכון ליד הפארק. = The high school is next to the park.

Because Hebrew often omits is in the present tense, this is a perfectly normal complete sentence.

However, without context, the words themselves could also be understood as a noun phrase:

• התיכון ליד הפארק = the high school next to the park

In actual use, punctuation and context usually make the meaning clear.

Hebrew often uses the same basic order here as English:

• התיכון = the subject
• ליד הפארק = a prepositional phrase describing location

So the structure is:

• [subject] + [location]
• התיכון + ליד הפארק

This is the normal way to say where something is in present-tense Hebrew when there is no spoken is.

A common pronunciation is:

ha-ti-KHON le-YAD ha-PARK

More smoothly: hatikhon leyad hapark

Notes:

• תיכון is stressed on the last syllable: ti-KHON
• ליד is stressed on the second syllable: le-YAD
• פארק is usually pronounced like park, with Hebrew sounds around it

It could be. Hebrew has a few ways to talk about a school.

• בית ספר = school
• בית ספר תיכון = high school
• תיכון = high school (shorter, very common)

So these are both possible:

• התיכון ליד הפארק. = The high school is next to the park.
• בית הספר התיכון ליד הפארק. = The high school is next to the park.

The version with תיכון alone is shorter and very natural in everyday Hebrew.

Yes. תיכון is masculine singular.

In this sentence, that does not create any visible change, because there is no adjective or verb form showing gender.

But gender would matter in other sentences. For example:

• התיכון גדול. = The high school is big.
  • גדול is the masculine singular form.

If the noun were feminine, the adjective would usually change too.
