Мама сошьёт мне тёплый халат.

Сошьёт is the perfective future form of сшить, which means to sew/make something and finish it.

So this form focuses on the completed result: the robe will get made.

• шить = to sew, to be sewing, to sew in general
• сшить = to sew something together, to make by sewing, to finish sewing

Compare:

• Мама шьёт халат. = Mom is sewing a robe / Mom sews robes.
• Мама будет шить халат. = Mom will be sewing a robe.
  This emphasizes the process.
• Мама сошьёт халат. = Mom will sew a robe (and it will be finished).
  This emphasizes the completed outcome.

In this sentence, Russian chooses the perfective form because the idea is that the robe will be made for someone.

Сошьёт is:

• 3rd person singular
• future tense
• perfective aspect
• from the verb сшить

So it matches Мама:

• Мама сошьёт = Mom will sew

The ending -ёт is the normal 3rd person singular ending for this verb form.

Yes, ё should be pronounced. It is not optional in careful learning.

Сошьёт is pronounced roughly sa-SHYOT.

A few helpful points:

• ё is almost always stressed
• it sounds like yo
• the шьё part sounds like shyo

So:

• сошьёт = sa-SHYOT
• not sa-SHET

In printed Russian, ё is sometimes replaced by е, but learners should remember that the real pronunciation is still ё.

Мне is the dative case of я.

Here it means for me or to me, depending on how you think about the action.

Russian often uses the dative for the person who receives something or benefits from an action.

So:

• Мама сошьёт мне халат = Mom will sew me a robe / sew a robe for me

Other forms of я for comparison:

• я = I
• меня = me
• мне = to me / for me
• мной = by me / with me

Yes, but the meaning would become less specific.

• Мама сошьёт тёплый халат. = Mom will sew a warm robe.
• Мама сошьёт мне тёплый халат. = Mom will sew me a warm robe.

With мне, the sentence clearly includes the person who will receive the robe.

Халат is in the accusative case, because it is the direct object of the verb: it is the thing being sewn.

However, for an inanimate masculine singular noun, the accusative form is usually the same as the nominative form.

So:

• nominative: халат
• accusative: халат

That is why it looks unchanged.

Тёплый has to agree with халат in:

• gender: masculine
• number: singular
• case: accusative

Since халат is masculine singular and inanimate, the adjective takes the matching form тёплый.

Compare:

• тёплый халат = warm robe
• тёплая рубашка = warm shirt
• тёплое пальто = warm coat
• тёплые вещи = warm clothes

Because with masculine inanimate nouns, the accusative usually looks the same as the nominative.

So:

• nominative: тёплый халат
• accusative: тёплый халат

But with a masculine animate noun, you would often see a different accusative form.

For example:

• nominative: новый брат
• accusative: нового брата

That difference happens because брат is animate, while халат is not.

Usually, yes. Халат often refers to a robe, dressing gown, or sometimes a loose indoor garment.

Depending on context, it can also mean things like:

• a bathrobe
• a house robe
• a medical coat or lab coat

In this sentence, with тёплый, it most naturally suggests a warm robe or dressing gown.

Because that is the most normal word order in Russian for a simple descriptive adjective.

• тёплый халат = warm robe

Russian adjectives usually come before the noun when they are just describing it.

Putting it after the noun is possible in some special styles or emphatic contexts, but it is not the normal neutral order here.

Yes. Russian word order is flexible, because case endings show the grammatical roles.

The neutral order here is:

• Мама сошьёт мне тёплый халат.

But you could also say:

• Мне мама сошьёт тёплый халат.
  Emphasis on for me
• Тёплый халат мама сошьёт мне.
  Emphasis on the warm robe
• Мама мне сошьёт тёплый халат.
  Also very natural

The basic meaning stays the same, but the focus changes.

Russian has no articles like English a or the.

So халат can mean:

• a robe
• the robe

Which one is intended depends on context.

In this sentence, English might naturally choose a warm robe, but Russian does not need a separate word to show that.

Usually it strongly suggests that she will make it by sewing, yes.

The verb сшить normally means to produce or make something by sewing it together. It implies an actual sewing action, not just buying or giving.

So the sentence presents Mom as the person who will create the robe through sewing.

Yes. мама is normally a common noun, not a proper name, so it is usually written with a lowercase letter unless it begins the sentence.

So here Мама is capitalized simply because it is sentence-initial.

A neutral pronunciation would usually stress the main content words, especially the verb and noun:

МАма сошьЁТ мне ТЁплый халаТ.

Approximate pronunciation:

• Мама = MA-ma
• сошьёт = sa-SHYOT
• мне = mnye
• тёплый = TYOP-lyy
• халат = kha-LAT

The exact intonation can change depending on what is being emphasized. For example:

• Мне мама сошьёт тёплый халат.
  Stronger focus on for me
• Мама сошьёт мне тёплый халат.
  Focus on what kind of thing she will sew

Yes. In fact, that is the most natural interpretation.

Because сошьёт is perfective, it normally refers to one completed future event: Mom will sew and finish the robe.

It does not sound like a habitual action such as Mom sews me warm robes regularly. For a habitual meaning, Russian would normally use an imperfective verb and a different context.
