La rozadura tiene pelusa.

Spanish often uses the definite article more than English does. Here, la rozadura refers to a specific chafed spot, sore, or abrasion that is already identifiable from the context.

So la rozadura tiene pelusa sounds like the abrasion/chafed area has lint on it, not just a general statement about abrasions in general.

If you said just rozadura tiene pelusa, it would sound incomplete or unnatural in normal Spanish.

Rozadura usually refers to skin irritation or a mark caused by rubbing or friction.

Depending on context, it can be:

• chafing
• a rubbed sore
• an abrasion
• sometimes something close to a blistered/rubbed area

In Spain, it is commonly used for irritation caused by shoes, clothing, or repeated rubbing.

Because its grammatical gender is feminine: la rozadura.

There is no special reason you need to calculate from the sentence itself—you simply learn the noun with its article. That said, nouns ending in -ura are very often feminine, so la rozadura fits a common pattern.

Examples:

• la rotura
• la cerradura
• la quemadura
• la rozadura

Tiene is the él/ella/usted form of tener in the present tense.

Here, the subject is la rozadura, which is grammatically singular, so Spanish uses tiene:

• la rozadura tiene

Even though English might sometimes prefer something like there is lint on it or it has lint on it, Spanish naturally uses tener for this kind of idea.

Spanish often lets objects or body-related things have qualities or things attached to them:

• La camisa tiene una mancha. = The shirt has a stain.
• La herida tiene pus. = The wound has pus.

So la rozadura tiene pelusa is grammatically very normal.

Here, pelusa means lint, fluff, or fuzz—small soft fibers, like the bits of fabric or dust that can stick to clothes or skin.

In other contexts, pelusa can also refer to:

• fine body hair or fuzz
• soft fluff on fabric or objects

But in this sentence, the most likely meaning is lint/fuzz stuck to the abrasion.

Because pelusa is being used like a mass noun, similar to lint or dust in English.

So:

• tiene pelusa = it has lint / it has fluff on it

You do not need una here unless you mean a specific piece or amount in a more countable way, which would be less natural in this sentence.

Compare:

• Tiene pelusa. = It has lint on it.
• Tiene una pelusa. = It has a piece/clump of lint on it.
  This is possible, but more specific.

Yes, but the meaning changes slightly.

• La rozadura tiene pelusa focuses on the abrasion having lint on it.
• La rozadura está sucia means the abrasion is dirty, which is broader and less specific.
• Hay pelusa en la rozadura means there is lint in/on the abrasion, which is also possible, but it presents the lint as existing there rather than describing the abrasion as having it.

So tener is a very natural choice when describing what is on or attached to something.

Yes, grammatically it is natural.

However, it is a bit specific and depends heavily on context. It sounds like something someone might say when checking an irritated patch of skin and noticing that lint from clothing, socks, or fabric has stuck to it.

So it is not an everyday textbook sentence, but it is perfectly understandable and structurally normal.

In Spain Spanish, rozadura is pronounced approximately:

ro-tha-DU-ra

More carefully:

• ro as in a short Spanish ro
• za with the Spain z sound, like th in think
• stress on du: ro-za-DU-ra

IPA (Spain): /ro.θaˈðu.ɾa/

And pelusa is roughly:

peh-LU-sa

IPA: /peˈlu.sa/

Yes, but the neutral, most straightforward order is:

La rozadura tiene pelusa.

That is: subject + verb + object

You might hear different word orders in special contexts, but they would usually sound marked or emphasize something:

• Pelusa tiene la rozadura. → unusual in normal speech
• Tiene pelusa la rozadura. → possible, but more marked, maybe if contrasting it with something else

For learners, the standard order is the best choice.

In this sentence, you have the third person singular:

• tiene = he/she/it has; you have (formal)

Present tense of tener:

• yo tengo
• tú tienes
• él/ella/usted tiene
• nosotros/nosotras tenemos
• vosotros/vosotras tenéis
• ellos/ellas/ustedes tienen

Since la rozadura is singular, it takes tiene:

• La rozadura tiene pelusa.

If the subject were plural:

• Las rozaduras tienen pelusa. = The abrasions have lint.
