זה אימייל רשמי, והיה מצורף אליו גם מסמך רשמי מהעירייה.

Because אימייל is treated as a masculine singular noun in Hebrew, so זה is the matching form of this.

Also, in a sentence like זה אימייל רשמי, Hebrew does not use a separate present-tense word for is. So the structure is literally close to:

this official email

but it means:

This is an official email.

So זה here is doing the job of this is.

In Hebrew, adjectives normally come after the noun they describe.

So:

• אימייל רשמי = an official email
• מסמך רשמי = an official document

This is the normal Hebrew word order:

• noun + adjective

whereas English usually uses:

• adjective + noun

רשמי is the masculine singular form of official, and it has to agree with the noun it describes.

In this sentence, both אימייל and מסמך are masculine singular, so רשמי is the correct form both times.

Some other forms are:

• רשמית = feminine singular
• רשמיים = masculine plural
• רשמיות = feminine plural

So the ending is not random; it shows agreement.

Literally, it breaks down like this:

• ו־ = and
• היה = was
• מצורף = attached / enclosed

So והיה מצורף means something like:

and was attached
or more naturally in English:
and there was also attached

In better English, the whole clause becomes:

and an official document from the municipality was also attached to it.

This is a very common Hebrew way to express something passive-like in the past: היה + participle.

Because מסמך is the subject of that part of the sentence, and it is masculine singular, so the verb is also masculine singular: היה.

Hebrew often allows the verb to come before the subject, especially in more formal or written styles.

So the structure is roughly:

and was attached to it also an official document...

Even though that sounds unusual in English, it is perfectly normal in Hebrew.

מצורף comes from the root צ־ר־ף and here means attached, enclosed, or included as an attachment.

In modern usage, especially with emails and documents, מצורף is very common for something that is attached.

For example:

• מצורף קובץ = a file is attached
• מצורף מסמך = a document is attached

So in this sentence, it refers to an attached document.

אליו is made of:

• אל = to
• ־יו = him / it for a masculine singular noun

So אליו literally means to him or to it.

Here it refers back to אימייל, which is a masculine noun, so in English we translate it as to it:

attached to it

A useful thing to remember is that Hebrew does not separate him and it the way English does when using these suffixes for masculine nouns. The same form can refer to a person or to an object, depending on context.

גם means also or too.

In this sentence, it shows that in addition to the email itself, there was also an attached official document.

Its position is natural Hebrew:

והיה מצורף אליו גם מסמך רשמי...

This placement connects גם closely with מסמך רשמי, meaning:

also an official document

מהעירייה is made of:

• מ־ = from
• העירייה = the municipality / city hall

So together it means:

from the municipality
or
from city hall

The ה is the definite article the, so this sounds like a specific municipality already known from context.

Compare:

• מהעירייה = from the municipality
• מעירייה = from a municipality

Yes:

• זה = this / this is
• אימייל = email
• רשמי = official
• ו־ = and
• היה = was
• מצורף = attached
• אליו = to it
• גם = also
• מסמך = document
• רשמי = official
• מהעירייה = from the municipality / city hall

A very literal rendering would be:

This is an official email, and attached to it was also an official document from the municipality.

A more natural English version is:

This is an official email, and an official document from the municipality was also attached to it.
