بعد از اینکه مسواک زدی، لطفا حوله را در حمام بگذار.

بعد از اینکه means after or more literally after the fact that.

• بعد از = after
• اینکه = that / the fact that

In natural English, we usually just say after you brush your teeth, but Persian often uses بعد از اینکه + verb to introduce a full clause.

So:

• بعد از اینکه مسواک زدی = after you brushed your teeth / after you brush your teeth

A very common alternative is a more compact structure:

• بعد از مسواک زدن = after brushing your teeth

Both are natural.

Yes, زدن very often means to hit, but in Persian it is also used in many compound verbs.

Here, مسواک زدن is a fixed expression meaning to brush one’s teeth.

So:

• مسواک = toothbrush
• مسواک زدن = to brush one’s teeth

Even though the literal pieces might seem odd from an English perspective, you should learn مسواک زدن as one unit.

Examples:

• دندان‌هایم را مسواک زدم = I brushed my teeth
• مسواک بزن = brush your teeth

زدی is the simple past, second person singular, from زدن.

So literally:

• زدی = you hit / you did
• in this compound verb: you brushed

In this sentence, Persian uses the past form after بعد از اینکه in a way that can sound natural even when English might use either:

• after you brushed your teeth
• after you brush your teeth

So بعد از اینکه مسواک زدی can work in an instruction like After you brush your teeth...

Yes. زدی is informal singular — used with a friend, child, sibling, etc.

More formal or polite would be:

• بعد از اینکه مسواک زدید، لطفا حوله را در حمام بگذارید.

Comparison:

• زدی / بگذار = informal singular
• زدید / بگذارید = formal or plural

So the given sentence is speaking to one person informally.

را marks the direct object.

Here:

• حوله را = the towel as the thing being placed

It does not usually translate into a separate English word, but it tells you clearly that حوله is the object of بگذار.

So:

• حوله را در حمام بگذار = put the towel in the bathroom

Without را, the sentence may sound less specific or less standard in many contexts.

Because در حمام means in the bathroom, which expresses location.

• در = in / inside
• به = to / toward

This sentence is about where to leave the towel:

• در حمام بگذار = leave/put it in the bathroom

If you used به حمام, it would suggest motion to the bathroom, which is not the intended meaning here.

بگذار is the informal singular imperative of گذاشتن, which means to put, to place, or sometimes to leave.

So:

• بگذار = put / place / leave

In this sentence, a natural translation is:

• please put the towel in the bathroom or
• please leave the towel in the bathroom

Formal version:

• بگذارید

Yes, لطفا can move around quite freely.

This sentence has:

• بعد از اینکه مسواک زدی، لطفا حوله را در حمام بگذار.

But these are also natural:

• لطفا بعد از اینکه مسواک زدی، حوله را در حمام بگذار.
• بعد از اینکه مسواک زدی، حوله را لطفا در حمام بگذار.
  This is possible, though a bit less neutral.

The most natural positions are usually near the beginning of the sentence or just before the imperative.

Yes, absolutely.

These are both natural:

• بعد از اینکه مسواک زدی، لطفا حوله را در حمام بگذار.
• بعد از مسواک زدن، لطفا حوله را در حمام بگذار.

The difference is mainly structural:

1. بعد از اینکه + finite verb

   • more clause-like
   • after you brush(ed)

2. بعد از + verbal noun / infinitive-like form

   • more compact
   • after brushing

Both are common in Persian.

حمام can mean different but related things depending on context:

• bathroom
• bath
• public bath, in older or traditional contexts

In this sentence, در حمام most naturally means in the bathroom.

So:

• حوله را در حمام بگذار = put/leave the towel in the bathroom

The sentence follows a very common Persian pattern:

time clause + polite marker + object + object marker + location + imperative verb

Broken down:

• بعد از اینکه مسواک زدی = after you brushed your teeth
• لطفا = please
• حوله را = the towel
• در حمام = in the bathroom
• بگذار = put

Persian often puts the verb at the end of the clause. That is one of the biggest differences from English.

The comma separates the introductory time clause from the main command.

So:

• بعد از اینکه مسواک زدی، = after you brush your teeth,
• لطفا حوله را در حمام بگذار. = please put the towel in the bathroom.

In writing, this comma helps readability. In speech, there is usually a short pause there as well.

Yes. In Persian, مسواک زدن by itself normally implies brushing one’s teeth, even if teeth are not explicitly mentioned.

So مسواک زدی is naturally understood as:

• you brushed your teeth

If someone wanted to be more explicit, they could say:

• دندان‌هایت را مسواک زدی = you brushed your teeth

But in everyday Persian, that is often unnecessary because مسواک زدن already carries that meaning.
