Entorsa este la picior.

Because entorsă is the indefinite form, meaning a sprain, while entorsa is the definite form, meaning the sprain.

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

Examples:

• entorsă → entorsa
• casă → casa
• masă → masa

So entorsa is the normal way to say the sprain.

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

So the structure is:

• Entorsa = the sprain
• este = is
• la picior = at/in the leg-foot area

In everyday speech, Romanians often shorten este to e:

• Entorsa e la picior.

Both are correct. Este is a little fuller or more careful; e is more conversational.

Romanian very often uses la when talking about pain, injuries, or location on a body part.

So la picior is a very natural Romanian way to say that something is in/at the leg or foot area.

This pattern is common:

• Mă doare la cap. = My head hurts.
• Are o rană la mână. = He/She has a wound on the hand/arm.
• Are o entorsă la picior. = He/She has a sprain in the leg/foot.

Even if English might use in, on, or no preposition at all depending on the sentence, Romanian often prefers la in this kind of context.

Because in Romanian, body parts often appear without the definite article in expressions like this, especially after prepositions such as la.

So la picior means something like at the leg/foot area in a general sense.

If you want to be more specific, you can use the definite form:

• la piciorul drept = in the right leg/foot
• la piciorul stâng = in the left leg/foot

So the version without the article is not missing anything; it is just the normal idiomatic form here.

It can mean leg or foot, depending on context.

Romanian picior covers a wider area than either English word by itself. In medical or everyday contexts, it can refer to the lower limb generally, and the exact meaning depends on the situation.

So when learners see la picior, they should not always force a strict one-word English match. Context tells you whether it is closer to leg, foot, or the lower limb area more generally.

It is grammatical and understandable, but in many real-life situations Romanian would more naturally focus on the person who has the sprain:

• Are o entorsă la picior. = He/She has a sprain in the leg/foot.

Your sentence, Entorsa este la picior, focuses more directly on where the sprain is located. So it is fine, but it may sound a little more descriptive or explanatory than the more usual everyday phrasing.

Yes. E is the shorter, very common spoken form of este.

So these are both correct:

• Entorsa este la picior.
• Entorsa e la picior.

In conversation, e is extremely common. In more careful speech or writing, you may also see este.

The sentence uses a very normal, neutral Romanian word order:

• Entorsa
  • este
    • la picior

Romanian word order is somewhat flexible, but this version is the most straightforward.

You could move things around for emphasis, but that would usually sound marked or less neutral. For a learner, Entorsa este la picior is the safest pattern to copy.

A rough English-friendly guide is:

en-TOR-sa ES-te la pi-CHOR

A few notes:

• Entorsa is stressed on TOR
• este is stressed on ES
• picior is stressed on the last syllable: chor
• the ci in picior sounds like ch in cheese

A more Romanian-style approximation would be:

• en-TOR-sa ES-te la pee-CHOR

Because Romanian nouns often keep the same visible form after prepositions like la, especially in the singular.

So even though la governs the accusative, the noun picior still looks the same:

• picior
• la picior

This is normal and not something unusual about this sentence. Romanian case is often shown by articles or context rather than by a big change in the noun itself.
