Soia poate avea urme de muștar.

No. In soia, the -a is part of the word itself, not the definite article.

• soia = soy / soya
• It is a feminine singular noun
• The dictionary form is already soia

So in this sentence, soia simply means soy as a substance or ingredient.

poate avea means can have or may have.

• poate = can / may (3rd person singular of a putea = to be able to / can)
• avea = to have (infinitive of a avea)

Because soia is singular, the verb is also singular:

• soia poate = soy can / may
• not soia pot, because pot is plural or 1st person singular depending on context

In food-label language, poate avea is a normal way to say that something may contain or may have traces of something.

Both are possible in Romanian, but they feel a little different in style.

• poate avea = more compact, often seen in formal or written language, including labels
• poate să aibă = also correct, often more common in everyday speech

So:

• Soia poate avea urme de muștar.
• Soia poate să aibă urme de muștar.

Both are grammatical. On packaging, the shorter poate avea sounds very natural.

urme is the plural of urmă.

Literally, urmă can mean things like:

• trace
• mark
• sign

In food labeling, urme de... is the standard phrase for traces of...

So:

• urme de muștar = traces of mustard

This is an idiomatic and very common expression.

Because Romanian normally uses de after a noun like urme when saying traces of something.

So the structure is:

• urme de + noun

Examples:

• urme de muștar = traces of mustard
• urme de lapte = traces of milk
• urme de nuci = traces of nuts

Without de, the phrase would be ungrammatical.

Because Romanian often uses a bare noun after de when speaking about a substance or category in a general sense.

Here, muștar means mustard as a substance/ingredient, not the mustard.

So:

• urme de muștar = traces of mustard
• not urme de muștarul, which would sound wrong here

This is similar to English, where we also usually say traces of mustard, not traces of the mustard.

In this sentence, muștar is understood as mustard in the food/allergen sense.

Depending on context, muștar can refer to:

• mustard as a condiment
• mustard as an ingredient/allergen
• sometimes the plant, in other contexts

On a food label, it is naturally interpreted as the allergen/ingredient.

A simple pronunciation guide:

• soia ≈ SOY-ya
• poate ≈ POA-te
• avea ≈ a-VE-a
• urme ≈ OOR-me
• muștar ≈ moosh-TAR

Whole sentence, roughly:

SOY-ya POA-te a-VE-a OOR-me de moosh-TAR

A few useful notes:

• ș is pronounced like sh in ship
• Romanian r is usually trilled or tapped
• Romanian vowels are pronounced more clearly than in English

Yes. In natural English, this sentence is often translated as:

• Soy may contain traces of mustard.

Even though Romanian uses a avea = to have, English food-label style often prefers contain.

Romanian could also say:

• Soia poate conține urme de muștar.

That is also very natural and may sound even closer to standard English packaging language.

Here is the breakdown:

• Soia = subject
• poate = finite verb / modal verb
• avea = infinitive
• urme = direct object
• de muștar = prepositional phrase modifying urme

So the structure is basically:

[Subject] + [modal verb] + [infinitive] + [object]

That is:

Soia + poate + avea + urme de muștar

Yes. This kind of sentence is very common in ingredient and allergen warnings.

You may also see similar patterns such as:

• Poate conține urme de arahide. = May contain traces of peanuts.
• Poate conține urme de lapte. = May contain traces of milk.
• Poate conține urme de gluten. = May contain traces of gluten.

So this sentence is useful not just grammatically, but also as a very practical real-life pattern.
