يا تحط ازازة الميه في شنطة ضهر يا تحطها جنب الخيمة.

Here يا ... يا ... means either ... or ....

So the sentence pattern is:

• يا تحط ... يا تحطها ...
• either you put ... or you put it ...

This is not the vocative يا meaning O / hey as in calling someone. It is the same written word, but a different use.

تحط is the present-tense form you put.

In Egyptian Arabic, after يا ... يا ..., it is very common to use the present tense to present alternatives:

• يا تحط ... يا تحطها ...
• literally: either you put ... or you put it ...

In natural English, we may translate that as a command:

• Either put the water bottle in a backpack or put it next to the tent.

So even though the Arabic uses a present form, the overall meaning can still feel like an instruction or suggestion.

ازازة الميه literally means the bottle of the water.

Arabic often uses a noun + noun structure where English might use one compound noun:

• ازازة الميه = water bottle / bottle of water

So instead of making a single compound word like English water bottle, Arabic commonly builds it as:

• ازازة = bottle
• الميه = the water

Depending on context, the phrase can be understood as the water bottle or a bottle of water.

The ها is an attached object pronoun meaning it.

So:

• تحطها = you put it

It refers back to ازازة الميه.

Arabic often avoids repeating the full noun if it is already clear, just like English does:

• Put the water bottle in a backpack, or put it next to the tent.

Because ازازة is a grammatically feminine noun.

In Arabic, pronouns agree with the noun they refer to. Since ازازة is feminine singular, the pronoun is feminine singular too:

• ازازة → ها

So even though English uses it, Arabic still tracks grammatical gender.

شنطة ضهر means backpack.

Literally, it is something like:

• شنطة = bag
• ضهر = back

So the whole expression is basically back bag, meaning a bag worn on your back.

This is very natural in Egyptian Arabic. A more formal or Standard Arabic equivalent would be:

• حقيبة ظهر

جنب means next to, beside, or by.

So:

• جنب الخيمة = next to the tent

It is a very common everyday Egyptian word. In more formal Arabic, you might see بجانب instead.

Yes, this order is very natural.

Here the pattern is:

• verb + object + place
• تحط = put
• ازازة الميه = the water bottle
• في شنطة ضهر = in a backpack

So the structure is basically:

• put the water bottle in a backpack

Egyptian Arabic often uses this kind of verb-first order, especially when the subject you is understood and does not need to be said explicitly.

Yes, this is clearly Egyptian Arabic.

Some clues are:

• الميه instead of Standard Arabic الماء
• شنطة instead of the more formal حقيبة
• the overall conversational structure with يا ... يا ...

A more formal Standard Arabic version might be:

• إمّا أن تضع زجاجة الماء في حقيبة ظهر، وإمّا أن تضعها بجانب الخيمة.

So the sentence you were given is the everyday Egyptian way, not formal written Arabic.

In this sentence, تحط is most naturally understood as you put addressed to one male.

If you were speaking to one female, you would usually hear:

• تحطي

If you were speaking to more than one person, you would usually hear:

• تحطوا

So this exact form most naturally fits you singular masculine in spoken Egyptian.

Yes. Egyptian Arabic spelling is not completely standardized, so you may see small differences.

Examples:

• ازازة or إزازة
• الميه or المية
• ضهر or ظهر

A rough pronunciation of the sentence is:

• ya tiḥoṭ azāzet el-mayya fi shanṭet ḍahr, ya tiḥoṭṭaha gamb el-khēma

A few useful pronunciation notes:

• Egyptian ج is usually pronounced g, so جنب sounds like gamb
• خ is the throaty kh sound, so الخيمة includes that sound
• a word ending in ة often sounds like -et when it is linked to another word, so ازازة الميه is often heard like azāzet el-mayya, not just azāza el-mayya
