Olarul frământă lutul atâta timp cât lutul rămâne pe masă.

Because Romanian usually puts the definite article at the end of the noun, not before it.

• olar = potter
• olarul = the potter
• lut = clay
• lutul = the clay

So -ul here marks definiteness, roughly like English the.

Romanian often repeats the noun instead of replacing it with a pronoun, especially when that makes the sentence clearer.

So:

• Olarul frământă lutul ...
• ... cât lutul rămâne pe masă

is perfectly natural and very clear.

A pronoun could be possible in a different context, but repeating lutul avoids ambiguity and sounds straightforward.

Frământă is the 3rd person singular present tense of a frământa.

Here it means kneads or works/kneads by hand.

So:

• a frământa = to knead
• el/ea frământă = he/she kneads

In context, it can correspond to English kneads or is kneading, since Romanian does not have a separate compulsory progressive form like English does.

It is a fixed expression meaning as long as.

It introduces a clause that gives the time limit or condition for the action in the main clause.

Literally, it is something like for that much time as, but you should understand it as the Romanian equivalent of:

• as long as
• for as long as
• sometimes while, depending on context

Rămâne is the 3rd person singular present tense of a rămâne = to remain / to stay.

Romanian often uses the present tense in both parts of a sentence like this when describing a general situation, repeated action, or a condition:

• Olarul frământă...
• ...cât lutul rămâne...

That works much like English:

• The potter kneads the clay as long as the clay remains on the table.

Because pe is the normal preposition for something being on a surface.

So:

• pe masă = on the table / on a table

Compare:

• pe masă = on the table
• la masă = at the table / at mealtime
• sub masă = under the table

So pe is used because the clay is resting on top of the table.

This is a very common learner question.

Romanian often uses a bare noun after a preposition in location expressions where English would naturally say the.

So pe masă can often mean:

• on the table
• or on a table

depending on context.

If you say pe masa, you are making the noun explicitly definite:

• masa = the table

That is also possible, but pe masă is very natural in many everyday contexts.

Yes. Romanian word order is more flexible than English word order, although the version you have is perfectly normal.

For example, you could also say:

• Atâta timp cât lutul rămâne pe masă, olarul frământă lutul.

That puts more focus on the time/condition clause first.

The original sentence is a neutral, natural order:

• subject: Olarul
• verb: frământă
• object: lutul
• subordinate clause: atâta timp cât...

The two main vowels learners notice here are:

• ă = a short neutral vowel, similar to the a in English sofa
• â = a Romanian vowel with no exact English equivalent; it is a close central sound

Very rough approximations:

• frământă ≈ fruh-MUHN-tuh
• atâta ≈ uh-TUH-tuh
• rămâne ≈ ruh-MUH-nuh

These are only approximations. The sound written â is especially important to practice, because English does not really have it.

Yes, you may also encounter atât timp cât with the same meaning: as long as.

Both forms are used and understood. If you see either one, you can treat it as the same expression in practice.

Here lut works like a mass noun, similar to English clay.

Even mass nouns can take the definite article in Romanian when they refer to a specific material already known in the situation:

• lut = clay
• lutul = the clay

So lutul here means the specific clay the potter is working with, not clay in general.
