Poteca este lângă un izvor.

Because poteca is the definite form: the path / the trail.

The dictionary form is potecă = a path / a trail.
In Romanian, the definite article is usually attached to the end of the noun, not written as a separate word.

So:

• potecă = a path, a trail
• poteca = the path, the trail

This is one of the first big differences from English.

Romanian usually puts the at the end of the noun as a suffix.

So instead of a separate word like English the path, Romanian says:

• poteca = path + the

This happens very often in Romanian:

• băiat = boy

• băiatul = the boy

• casă = house
• casa = the house

So in your sentence, poteca already includes the idea of the.

Este means is.

It is the 3rd person singular present form of the verb a fi = to be.

So:

• eu sunt = I am
• tu ești = you are
• el/ea este = he/she/it is

In this sentence, Poteca este lângă un izvor, este links the subject poteca with the location phrase lângă un izvor.

Yes. In everyday Romanian, e is a very common shorter form of este.

So these both work:

• Poteca este lângă un izvor.
• Poteca e lângă un izvor.

The full form este may sound a little more careful or formal, while e is extremely common in normal speech.

Lângă means near, beside, or next to, depending on context.

In this sentence, it means the path is located close to the spring.

Examples:

• lângă casă = near the house
• lângă mine = next to me
• lângă drum = beside the road

So lângă is a very useful location preposition.

Because un is the indefinite article here, meaning a.

So:

• izvor = spring
• un izvor = a spring
• izvorul = the spring

The sentence uses un izvor because it refers to a spring, not a specific spring already identified as the spring.

Because izvor is not a feminine noun.

In Romanian, the singular indefinite articles are:

• un for masculine and neuter singular nouns
• o for feminine singular nouns

So:

• un izvor
• o potecă

A useful extra detail: izvor is a neuter noun. In Romanian, neuter nouns behave like masculine in the singular and feminine in the plural. That is why the singular uses un.

No. Here izvor means a natural spring, a place where water comes out of the ground.

It does not mean the season spring. The season is primăvară.

So:

• izvor = water spring, source
• primăvară = spring (season)

This is an important vocabulary distinction for English speakers.

The sentence follows a very normal Romanian order:

• Poteca = subject
• este = verb
• lângă un izvor = location phrase

So the structure is basically:

Subject + is + location

This is very similar to English:

• The path is near a spring.

Romanian word order can sometimes change for emphasis, but this version is the most straightforward and natural.

Yes, Romanian allows some flexibility, but the original order is the most neutral.

For example, you might also hear:

• Lângă un izvor este poteca.

That could sound more marked or literary, depending on context, with more focus on the location.

For a learner, Poteca este lângă un izvor is the best basic pattern to remember.

A simple learner-friendly guide would be:

po-TE-ka ES-te LÂN-gă un iz-VOR

A few important sound notes:

• ă is a short central vowel, something like the a in sofa
• â is a special Romanian vowel pronounced deeper in the center of the mouth
• g in lângă is a hard g, like in go
• stress falls roughly on:
  • poteca → te
  • lângă → lân
  • izvor → vor

You do not need perfect pronunciation immediately, but it helps to notice the special vowels ă and â early.

Yes. The base noun potecă is feminine.

You can see that in forms like:

• o potecă = a path
• poteca = the path

Many Romanian nouns ending in -ă are feminine, though not every noun pattern is completely predictable.

In standard Romanian, you normally keep este here.

So:

• Poteca este lângă un izvor. = correct

Leaving it out would not sound like standard English-style omission; Romanian generally uses the verb to be in sentences like this.

So for learners, it is safest to include este or e.

You would change poteca to o potecă.

So:

• Poteca este lângă un izvor. = The path is near a spring.
• O potecă este lângă un izvor. = A path is near a spring.

This shows the contrast clearly:

• attached article = definite
• separate un/o = indefinite

That definite/indefinite contrast is very important in Romanian.
