השדכן על השולחן, אבל המחורר בתוך המגירה.

In Hebrew, the present tense of to be is usually omitted.

So:

• השדכן על השולחן literally = the stapler on the table
• but it means the stapler is on the table

Likewise:

• המחורר בתוך המגירה = the hole punch is inside the drawer

If you want, you can sometimes add נמצא (is located / is found) for extra explicitness, but in normal everyday Hebrew it is usually left out.

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

So:

• שדכן = a stapler

• השדכן = the stapler

• שולחן = a table

• השולחן = the table

• מחורר = a hole punch / perforator

• המחורר = the hole punch

• מגירה = a drawer
• המגירה = the drawer

Hebrew adds the directly to the beginning of the noun instead of using a separate word.

שדכן here means stapler.

Be aware that Hebrew words can sometimes have more than one meaning in different contexts. In older or different contexts, שדכן can also mean matchmaker, but in a sentence about office objects like this one, it clearly means stapler.

מחורר literally comes from a root related to making holes / perforating. As a form, it can look like a participle or adjective, but in modern everyday Hebrew it can also function as a noun meaning hole punch or perforator.

So in this sentence:

• המחורר = the hole punch

This is common in Hebrew: a participle-looking form can become the normal name for a tool or device.

They describe different kinds of location:

• על = on
• בתוך = inside / within

So:

• על השולחן = on the table
• בתוך המגירה = inside the drawer

Using בתוך emphasizes that the object is inside the drawer, not just associated with it.

Both are possible, but they are slightly different.

• במגירה = in the drawer
• בתוך המגירה = inside the drawer

בתוך is a bit more explicit and can sound slightly more concrete or emphatic about being physically inside.

Also notice the grammar:

• במגירה combines ב (in) with the into one word
• but בתוך is a separate word, so the noun still keeps its own ה:
  • בתוך המגירה

אבל means but.

It connects the two contrasting parts:

• השדכן על השולחן
• אבל המחורר בתוך המגירה

So the full idea is:

• The stapler is on the table, but the hole punch is inside the drawer.

Its placement is very natural here: after the first clause and before the second clause.

Yes, this word order is very normal.

The pattern is:

• [noun] + [location]
• [noun] + [location]

So:

• השדכן על השולחן
• המחורר בתוך המגירה

This is a common and natural way to express location in Hebrew, especially when there is no spoken is in the present tense.

Yes, absolutely.

• המחורר במגירה = the hole punch is in the drawer
• המחורר בתוך המגירה = the hole punch is inside the drawer

The second version is just a little more explicit. In many everyday situations, both would sound fine.

Yes, every Hebrew noun has grammatical gender, though in this sentence it does not change anything visible because there are no adjectives agreeing with the nouns.

Likely genders here are:

• שדכן — masculine
• שולחן — masculine
• מחורר — masculine
• מגירה — feminine

Gender becomes more noticeable when you add adjectives or use verbs in some tenses.

For example:

• המגירה גדולה = the drawer is big
  because מגירה is feminine

• השולחן גדול = the table is big
  because שולחן is masculine

A rough pronunciation is:

• ha-shad-KHAN al ha-shool-KHAN, a-VAL ha-mekho-RER be-TOKH ha-megi-RA

A few notes:

• שדכן has stress at the end: shad-KHAN
• שולחן also has final stress: shool-KHAN
• מחורר has stress on the last syllable: mekho-RER
• מגירה has stress on the last syllable: megi-RA

Exact pronunciation can vary slightly by speaker and accent.

Yes. You could say:

• השדכן נמצא על השולחן, אבל המחורר נמצא בתוך המגירה.

This means the same thing:
The stapler is located on the table, but the hole punch is inside the drawer.

However, this version sounds a bit heavier or more explicit. In ordinary speech, most speakers would usually prefer the shorter version without נמצא.

Yes. For example:

• המחורר בתוך המגירה, אבל השדכן על השולחן.

This is still correct. It just changes which fact comes first.

Hebrew is fairly flexible here, as long as the sentence remains clear. The original version is natural and straightforward.
