Lesa roz este pe masă.

Because Romanian usually puts the definite article at the end of the noun, not as a separate word like English the.

• lesă = a leash / leash
• o lesă = a leash
• lesa = the leash

So in this sentence, lesa is the definite form.

A useful pattern:

• feminine noun ending in -ă often becomes definite by changing -ă to -a
• lesă → lesa
• masă → masa

Because in Romanian, descriptive adjectives usually come after the noun in normal, neutral word order.

So:

• lesa roz = literally the leash pink
• natural English translation: the pink leash

Romanian can sometimes place an adjective before the noun, but that often sounds more emphatic, literary, or changes the nuance. For basic description, noun + adjective is the default.

Because roz is usually an invariable adjective in Romanian. That means it keeps the same form instead of changing for gender.

Examples:

• un câine roz = a pink dog
• o lesa roz = a pink leash
• o floare roz = a pink flower

So even though lesa is feminine, roz stays roz.

Este means is. It is the 3rd person singular present form of a fi (to be).

So:

• este = is

In everyday speech, Romanians very often use the shorter form e:

• Lesa roz e pe masă.

Both are correct. Este sounds a bit fuller or more careful; e is very common in conversation.

Here, pe means on.

So:

• pe masă = on the table / on a table

Later, you may also see pe used in another way, especially before people or other animate direct objects:

• Văd pe Maria = I see Maria

But in your sentence, it is just the normal preposition on.

This is a very common learner question.

Masă is the basic noun table, and after prepositions Romanian often allows a bare noun in location expressions. So pe masă is a very natural way to say where something is.

Depending on context, pe masă can be understood as:

• on the table
• on a table

Romanian often leaves that slightly more open than English does.

You can also hear pe masa, especially when the table is clearly specific or further defined:

• pe masa din bucătărie = on the table in the kitchen

So pe masă is not strange here; it is a normal locative phrase.

The letter ă is a special Romanian vowel. It sounds like a short, unstressed uh sound, somewhat like the final sound in English sofa for many speakers.

So:

• masă ≈ MAH-suh
• lesă ≈ LEH-suh

But notice the sentence has lesa, not lesă:

• lesă = leash
• lesa = the leash

That final vowel change matters.

Yes. Masă can mean:

• table
• meal

Context tells you which meaning is intended.

In pe masă, it clearly means table, because pe means on, so the phrase means something like on the table. A leash cannot literally be on a meal, so the meaning is clear.

Yes, Romanian word order is fairly flexible, although the original sentence is the most neutral.

Neutral:

• Lesa roz este pe masă.

You could also say:

• Pe masă este lesa roz.

That version puts more focus on the location: On the table is the pink leash.

So the original order is the standard, straightforward one, but Romanian can move things around for emphasis or style.
