Glazura este lucioasă.

In Romanian, the definite article is usually attached to the end of the noun, not placed before it like in English.

So:

• glazură = glaze / icing
• glazura = the glaze / the icing

That final -a is doing the job of English the.

Because glazura is the definite form of the noun.

For this feminine noun:

• o glazură = a glaze / an icing
• glazura = the glaze / the icing

This is a very common Romanian pattern with feminine nouns ending in -ă.

Este is the 3rd person singular form of a fi, which means to be.

So:

• glazura = the glaze
• este = is
• lucioasă = shiny / glossy

Together: The glaze is shiny.

This is a standard equational/descriptive sentence, just like English X is Y.

Yes. E is a very common short form of este in everyday Romanian.

So both are correct:

• Glazura este lucioasă.
• Glazura e lucioasă.

The full form este sounds a bit more neutral or careful; e is more conversational.

Because Romanian adjectives agree with the noun they describe in gender and number.

Glazura is a feminine singular noun, so the adjective must also be feminine singular:

• masculine singular: lucios
• feminine singular: lucioasă
• masculine plural: lucioși
• feminine plural: lucioase

Since glazura is feminine singular, lucioasă is the correct form.

One strong clue is the indefinite form:

• o glazură = a glaze / an icing

If a noun takes o in the singular, it is feminine.

You also see the adjective agreeing in the feminine form:

• glazura este lucioasă

So both the article pattern and the adjective agreement show that glazură is feminine.

It mainly means shiny, glossy, or lustrous.

It refers to something that reflects light or has a polished appearance. Depending on context, English might translate it as:

• shiny
• glossy
• lustrous

It does not primarily mean slippery. For slippery, Romanian would normally use a different word, such as alunecos / alunecoasă.

Yes. Glazură / glazura can refer to different kinds of glaze or coating, depending on the situation.

For example, it can mean:

• the icing on a cake or pastry
• a glossy coating on food
• glaze on ceramics or pottery
• sometimes another kind of surface coating

So the exact English translation depends on context, even though the grammar of the sentence stays the same.

This is the normal, neutral word order:

• subject + verb + adjective

So Glazura este lucioasă is the most natural way to say it.

Romanian can sometimes change word order for emphasis, but that would sound marked or stylistic. For a learner, this standard order is the best one to use.

A rough English-friendly guide is:

• glazura ≈ glah-ZOO-rah
• este ≈ ES-teh
• lucioasă ≈ loo-chee-WAH-suh

A few useful pronunciation points:

• ci in lucioasă sounds like chee
• ș sounds like English sh
• ă is a short central vowel, something like the final sound in sofa

Romanian spelling is fairly regular, so once you learn these letters and sounds, pronunciation becomes much easier.

It would be:

• Glazurile sunt lucioase.

That means The glazes are shiny or The icings are shiny, depending on context.

Here is what changes:

• glazura → glazurile = the glazes
• este → sunt = are
• lucioasă → lucioase = feminine plural adjective

This is a good example of how both the noun and adjective change in Romanian.
