Su hija tiene el pelo rubio como su madre.

In Spanish, su is a third-person/fomal possessive that can mean:

• his
• her
• its
• your (formal singular)
• their
• sometimes your (formal plural, depending on variety)

So Su hija could mean his daughter, her daughter, their daughter, or your daughter in a formal context. Spanish often relies on context to make this clear.

In this sentence, the most natural reading is simply his/her daughter.

Spanish very often describes hair with the pattern:

tener + el pelo + adjective

So:

• Tiene el pelo rubio = She has blonde hair

This is more idiomatic than translating English word-for-word.

You can also say:

• Su hija es rubia

That means His/Her daughter is blonde, and it describes the person directly. Both are correct, but:

• tiene el pelo rubio focuses specifically on the hair
• es rubia describes the person as blonde in general

In Spanish, when talking about parts of the body or something closely associated with a person, the definite article is often used where English would use a possessive.

So Spanish prefers:

• Tiene el pelo rubio

rather than:

• Tiene su pelo rubio

Using su pelo is not impossible, but it would usually sound more marked or emphatic, as if you were contrasting her hair with someone else’s.

In a neutral sentence, el pelo is the natural choice.

Because rubio agrees with pelo, not with hija.

• pelo is masculine singular
• so the adjective must be rubio

That is why the sentence says:

• el pelo rubio

If you described the daughter directly, then the adjective would agree with hija:

• Su hija es rubia

So compare:

• Su hija tiene el pelo rubio = adjective agrees with pelo
• Su hija es rubia = adjective agrees with hija

Here como su madre means like her mother or like his/her mother.

The idea is:

• His/Her daughter has blonde hair, like her mother does

It implies that the mother also has blonde hair.

In other words, como su madre compares the daughter to the mother with respect to the hair description.

A little, yes. Grammatically, su madre can be ambiguous for the same reason su hija is ambiguous: su can mean his, her, your, or their depending on context.

But in normal use, the intended meaning is usually obvious. Here, the natural interpretation is:

• the daughter has blonde hair
• and the mother does too

So the sentence is understood as Her daughter has blonde hair like her mother.

Yes, absolutely.

• Su hija es rubia como su madre = His/Her daughter is blonde like her mother
• Su hija tiene el pelo rubio como su madre = His/Her daughter has blonde hair like her mother

Both are natural, but there is a slight difference in focus:

• es rubia describes the daughter herself
• tiene el pelo rubio focuses more specifically on the hair

In many situations, both would work fine.

Because como by itself can mean like in comparisons.

So:

• como su madre = like her mother

You do not need que here.

Spanish uses como alone for this kind of comparison, just as English uses like.

Yes. Both can mean hair, but there is a slight difference in tone:

• pelo = the most common everyday word
• cabello = often a bit more formal or stylistic

So:

• Tiene el pelo rubio is very natural and common
• Tiene el cabello rubio is also correct, but sounds a bit more formal or literary

For everyday Spanish, pelo is usually the best choice.

The given word order is the most natural:

• Su hija tiene el pelo rubio como su madre

You could make small changes, but they may sound less neutral or require punctuation. For example:

• Su hija, como su madre, tiene el pelo rubio
• Como su madre, su hija tiene el pelo rubio

These versions are possible, but they put extra emphasis on the comparison with the mother.

So for a standard sentence, the original order is the best one.

Yes. Rubio/rubia usually means blonde or fair-haired.

In real life, what counts as rubio can be a bit broader than English blonde. Depending on context, it can include hair that is:

• very blonde
• dark blonde
• light brown with a fair/blonde tone

But in most learning contexts, the best translation is simply blonde.

Spanish often leaves that kind of repeated idea implied.

English often says:

• like her mother does

Spanish can simply say:

• como su madre

The full idea is understood from the sentence. Spanish often avoids repeating information when it is already clear from context.
