La cucitura tiene la tomaia.

Because cucitura and tomaia are both feminine singular nouns in Italian.

• la cucitura = the seam / the stitching
• la tomaia = the upper (the upper part of a shoe)

So the article la agrees with each noun in gender and number.

Cucitura is a noun, not a verb. It comes from the idea of sewing, but in this sentence it means something like:

• seam
• stitching
• line of stitching

In a technical or manufacturing context, cucitura often refers to the sewn part that joins materials together.

Tiene is the 3rd person singular, present indicative of tenere.

So:

• io tengo = I hold / keep
• tu tieni = you hold / keep
• lui/lei tiene = he/she/it holds / keeps

Here the subject is la cucitura, which is singular, so the verb must also be singular: tiene.

Because tenere is an irregular verb in the present tense. Its stem changes in some forms:

• tengo
• tieni
• tiene
• teniamo
• tenete
• tengono

So tiene is simply the correct present-tense form for he/she/it.

Because la tomaia is the direct object of the verb tenere.

In this sentence:

• La cucitura = subject
• tiene = verb
• la tomaia = direct object

Italian, like English, does not normally use a preposition before a direct object here.

So the structure is just:

subject + verb + object

In this sentence, tenere means something like:

• to hold
• to keep in place
• to keep together

It does not mean to own here.
Italian tenere has several meanings depending on context, including hold, keep, retain, or maintain.

In a physical/material context like this one, holds or keeps in place is the best interpretation.

Tomaia is a fairly specialized word. It means the upper part of a shoe—the material that covers the top and sides of the foot.

It is common in:

• shoemaking
• footwear repair
• product descriptions
• technical discussions about shoes

A learner might not meet it very often outside those contexts.

Yes. La cucitura tiene la tomaia follows the normal Italian pattern:

• subject: La cucitura
• verb: tiene
• object: la tomaia

This is the most straightforward and neutral order. Italian can change word order for emphasis, but this version is the standard one.

Yes, depending on context. In technical English, possible translations could include:

• The stitching holds the upper.
• The stitching secures the upper.
• The seam keeps the upper in place.

The exact English choice depends on how technical or natural you want the translation to sound.

A simple pronunciation guide is:

lah koo-chee-TOO-rah TYEH-neh lah toh-MY-ah

A few helpful points:

• cuci- in cucitura sounds like koo-chee
• tiè in tiene is pronounced like tyeh
• tomaia has stress on -mai-

So the natural stress is:

la cuciTÙra tiÈne la toMÀia

Sometimes, yes, depending on the nuance you want.

For example:

• La cucitura sostiene la tomaia = The stitching supports the upper
• La cucitura fissa la tomaia = The stitching fixes/secures the upper
• La cucitura unisce la tomaia = The stitching joins the upper

But tiene is a good general verb if the idea is that the stitching is holding the upper in place. Different verbs give slightly different shades of meaning.
