Glazurăm marginea fie cu buretele, fie cu pensula.

Glazurăm is the 1st person plural, present tense form of a glazura.

So literally it means we glaze.

In Romanian instructions, recipes, tutorials, and demonstrations, this we form is very common. It often does not mean a literal group of people; it is just a natural way to guide the reader through the steps. In English, this can feel like:

• we glaze the edge
• let’s glaze the edge
• sometimes simply an instruction like glaze the edge

So the form is grammatical we, but the function is often instructional.

Romanian word order is fairly flexible, and starting with the verb is very normal in instructions.

Beginning with glazurăm puts the focus on the action first, which is especially common in procedural language.

This sentence could also be rearranged, but the given order sounds natural and efficient:

• Glazurăm marginea... = natural for instructions
• Noi glazurăm marginea... = possible, but noi is usually unnecessary unless you want emphasis

So the verb-first order here is not strange; it is actually very typical.

Because marginea means the edge, while margine means just edge as the basic dictionary form.

Romanian usually marks definiteness by adding the article to the end of the noun:

• margine = edge
• marginea = the edge

Here the speaker means a specific edge, not just any edge, so the definite form is used.

Unlike English, Romanian usually puts the definite article at the end of the noun instead of using a separate word like the.

In this sentence:

• margine → marginea = the edge
• burete → buretele = the sponge
• pensulă → pensula = the brush

This is one of the first big differences English speakers notice in Romanian.

So instead of:

• English: the edge
• Romanian: marginea

the article is attached directly to the noun.

Because pensulă is the basic indefinite form, while pensula is the definite form.

• pensulă = a brush / brush
• pensula = the brush

So the final -ă changes when the definite article is added. This is normal for many feminine nouns in Romanian.

Fie ..., fie ... means either ..., or ....

So:

• fie cu buretele, fie cu pensula
  means
• either with the sponge or with the brush

This structure presents two alternatives. It is common in explanatory or instructional language and sounds a bit more deliberate or structured than a simple sau.

Because Romanian normally repeats the preposition in each half of this kind of paired structure.

Each option is a complete phrase:

• cu buretele
• cu pensula

When they are linked with fie ..., fie ..., repeating cu makes the sentence balanced and clear.

So Romanian prefers:

• fie cu buretele, fie cu pensula

rather than trying to make one cu cover both items.

In Romanian instructions, tools are very often expressed with the definite form, especially after cu.

So:

• cu buretele
• cu pensula

sounds natural in a practical, step-by-step context.

English may choose either:

• with the sponge / with the brush
• with a sponge / with a brush

depending on style and context. Romanian often leans more naturally toward the definite form in sentences like this.

So the Romanian definite article does not always map perfectly onto English the in a rigid word-for-word way.

Because Romanian is a pro-drop language, which means the subject pronoun is often omitted when the verb ending already shows who is doing the action.

Here, glazurăm already tells you the subject is we.

So:

• glazurăm = we glaze

Adding noi is possible, but it usually adds emphasis, contrast, or special focus:

• Noi glazurăm marginea... = we glaze the edge...

Without that emphasis, Romanian normally leaves the pronoun out.

Yes.

Possible alternatives include:

• Glazurăm marginea cu buretele sau cu pensula.
• Glazurăm marginea ori cu buretele, ori cu pensula.

The differences are mainly about style:

• sau = simple, neutral or
• ori ..., ori ... = either ..., or ...
• fie ..., fie ... = also either ..., or ..., often sounding a bit more formal, careful, or instructional

So the original sentence is not the only correct way, but it is a very natural one.
