אנחנו תורמות את הבגדים מהערימה בנקודת הנתינה וההחלפה.

Because the speaker is referring to אנחנו = we, and the verb/adjective-like present-tense form must agree with the gender/number of the people doing the action.

• תורמות = feminine plural
• תורמים = masculine plural or mixed-gender plural

So this sentence sounds like it is being said by a group of women. If the group were men or mixed, you would normally say:

אנחנו תורמים את הבגדים מהערימה בנקודת הנתינה וההחלפה.

Yes. In modern Hebrew, present-tense verbs often look like adjective-like participle forms and agree with gender and number.

Here are the present forms of לתרום = to donate:

• תורם = masculine singular
• תורמת = feminine singular
• תורמים = masculine/mixed plural
• תורמות = feminine plural

So אנחנו תורמות means we donate / we are donating, depending on context.

את marks a definite direct object. It does not really translate into English, but it tells you that the noun after it is the specific thing receiving the action.

Here:

• תורמות = donate
• את הבגדים = the clothes as the direct object

You use את because הבגדים is definite: the clothes.

Compare:

• אני תורמת בגדים. = I donate clothes.
  No את, because clothes is indefinite.

• אני תורמת את הבגדים. = I donate the clothes.
  את is required because the clothes is definite.

The prefix ה־ means the.

So:

• בגדים = clothes
• הבגדים = the clothes

Since the sentence refers to a specific set of clothes, Hebrew uses הבגדים. And because it is definite, it also takes את: את הבגדים.

מהערימה is made from:

• מ־ = from
• הערימה = the pile

So:

• ערימה = pile
• הערימה = the pile
• מהערימה = from the pile

When מ־ comes before a word with ה־, they usually contract together in pronunciation and spelling like this.

Because נקודת is in the construct state.

Hebrew often uses a noun + noun structure to mean the X of Y. In this structure, the first noun changes form and goes into construct state.

Here:

• נקודה = point
• נקודת = point of ...

So:

• בנקודת הנתינה וההחלפה = at the point of giving and exchange

If you said בנקודה, that would mean at a point or at the point, but it would not naturally connect to the following nouns in the same way.

It is a construct chain plus a coordinated noun.

Breakdown:

• נקודת = point of
• הנתינה = the giving / the donation
• וההחלפה = and the exchange

So literally it is something like:

the point of the giving and the exchange

In more natural English, this might be rendered as the donation and exchange point or the giving-and-swapping point, depending on context.

Because both nouns are definite:

• הנתינה = the giving / the donation
• ההחלפה = the exchange

And ו־ means and, so:

• וההחלפה = and the exchange

In Hebrew, when two coordinated nouns are both definite, each one usually gets its own definite article:

• הנתינה וההחלפה
• literally: the giving and the exchange

It could be left out.

Hebrew often omits subject pronouns when the verb form already makes the subject clear enough.

So both are possible:

• אנחנו תורמות את הבגדים...
• תורמות את הבגדים...

Including אנחנו can add clarity, emphasis, or simply sound more explicit. Since תורמות already shows plural feminine, the pronoun is not strictly required.

Yes, Hebrew word order is somewhat flexible, though some orders sound more neutral than others.

The given sentence has a very natural order:

• אנחנו תורמות את הבגדים מהערימה בנקודת הנתינה וההחלפה.

You might also hear variations depending on emphasis, for example:

• את הבגדים מהערימה אנחנו תורמות בנקודת הנתינה וההחלפה.

That version puts extra focus on the clothes from the pile. But for a learner, the original order is the safest and most standard to use.

Grammatically, נתינה is a verbal noun from לתת = to give, so its core sense is giving.

But in context, Hebrew often uses verbal nouns in places where English might prefer a more specific noun like donation. So depending on the situation, נקודת הנתינה could be understood as:

• the giving point
• the donation point
• the drop-off point

So the exact English wording may change, but the Hebrew structure is normal.

You would change תורמות to תורמים.

So:

• אנחנו תורמות... = we donate / are donating ...
  said by women

• אנחנו תורמים... = we donate / are donating ...
  said by men or a mixed group

The rest of the sentence stays the same.
