Положи решётку на мангал, а я принесу шампуры.

Положи is the informal singular imperative of положить, so it means put! / place!

A few things are happening here:

• положить is a perfective verb
• the imperative положи tells someone to do the action as a single completed act
• it sounds natural when you mean put it down / place it there

In this sentence, the speaker is telling one person casually to do something:

• Положи решётку на мангал = Put the grill grate onto the brazier

If you were speaking:

• to several people, or
• to one person formally,

you would say положите.

Compare:

• клади / кладите = more like be putting / put it down in an imperfective sense
• положи / положите = put it (and have it placed there)

In everyday instructions, положи is very common.

Решётку is the accusative singular of решётка.

The noun решётка is feminine, and in this sentence it is the direct object of the verb положи. In other words, it is the thing being put somewhere.

Forms:

• nominative: решётка
• accusative: решётку

So:

• решётка = a grill grate / grid / rack as a dictionary form
• положи решётку = put the grate

This is a very common pattern in Russian:

• verb + direct object in the accusative

Because на can take different cases depending on the meaning.

Here the idea is movement onto something, so Russian uses:

• на + accusative

That gives:

• на мангал = onto the brazier / onto the grill setup

Compare:

• Положи решётку на мангал. = Put the grate onto the brazier.
• Решётка лежит на мангале. = The grate is on the brazier.

So the contrast is:

• на + accusative = direction / destination
• на + prepositional = location

Why does мангал look unchanged here?
Because мангал is masculine inanimate, and its accusative singular is the same as its nominative singular:

• nominative: мангал
• accusative: мангал
• prepositional: мангале

In this sentence, а is not just a simple and. It often marks a contrast, shift, or division of roles.

So:

• Положи решётку на мангал, а я принесу шампуры.

has the sense of:

• You put the grate on the brazier, and I’ll bring the skewers.

The idea is:

• you do this
• I’ll do that

Russian often uses а when two different subjects are doing different things.

Compare very roughly:

• и = simple addition: and
• а = and meanwhile / while / whereas / as for the other part

Here а sounds very natural because the speaker is assigning complementary actions.

Принесу is the 1st person singular future of the verb принести, meaning I will bring.

So:

• я принесу = I will bring

Important point: принести is a perfective verb, so its future is expressed with a simple future form:

• принесу = I will bring

This emphasizes a completed result: the speaker will go and bring the skewers.

Compare:

• приносить = imperfective, to bring in a repeated or ongoing sense
• принести = perfective, to bring as a completed action

So if you say я принесу шампуры, it sounds like:

• I’ll go get the skewers and bring them here

Шампуры is the accusative plural of шампур.

Since шампуры are the direct object of принесу, they need the accusative.

For inanimate masculine plural nouns, the accusative is usually the same as the nominative:

• nominative plural: шампуры
• accusative plural: шампуры

So:

• шампуры = skewers
• принесу шампуры = I’ll bring the skewers

Singular and plural:

• шампур = one skewer
• шампуры = skewers

These are very common barbecue-related words in Russian-speaking contexts.

• мангал = a metal charcoal brazier, often used outdoors for grilling meat
• решётка = a grill grate / grill rack
• шампуры = skewers, especially metal skewers used for шашлык

So the scene is probably outdoor cooking, where someone is preparing the grill setup.

A мангал is not exactly the same as an American-style barbecue grill with a lid. It often refers to an open metal container for coals, especially for cooking шашлык.

Because both actions are viewed as single completed tasks.

• положи = put it in place
• принесу = I’ll bring them

This is very natural when people are organizing practical actions step by step.

Russian often chooses the perfective when the speaker cares about the result:

• the grate ends up on the brazier
• the skewers end up brought

If the sentence used imperfective verbs, it would sound different in nuance, often more about process, repetition, or ongoing action.

So in this context, perfective verbs fit the situation very well:

• short instruction
• clear result
• one-time actions

The word order is natural, but Russian word order is fairly flexible.

The sentence:

• Положи решётку на мангал, а я принесу шампуры.

sounds neutral and natural:

1. command
2. object
3. destination
4. contrast
5. subject
6. future action
7. object

You could rearrange parts for emphasis, but the original order is probably the most natural in everyday speech.

For example, Russian could move words around to stress different things, but that would change the feel:

• На мангал положи решётку...
  More emphasis on onto the brazier

• Шампуры принесу я...
  More emphasis on I or on the skewers

So the original word order is a good standard model for learners.

You would change the imperative положи to положите.

So:

• Положите решётку на мангал, а я принесу шампуры.

This can mean:

• speaking politely to one person
• speaking to several people

That is a very important Russian pattern:

• положи = informal singular
• положите = formal singular or plural

The rest of the sentence stays the same.

A natural stress pattern is:

• Положи́ решётку на манга́л, а я принесу́ шампуры́.

Useful notes:

• ё is always stressed, so решётку automatically has stress on ё
• мангал is stressed манга́л
• принесу is принесу́
• шампуры is commonly шампуры́

A rough pronunciation guide:

• положи́ = pa-la-ZHEE
• решётку = ri-SHYOT-ku
• манга́л = man-GAHL
• принесу́ = pri-ni-SOO
• шампуры́ = sham-pu-RY

If spoken naturally, there is usually a short pause before а я:

• Положи́ решётку на манга́л, | а я принесу́ шампуры́.
