Nuestra profesora es exigente, aunque siempre corrige con paciencia y con respeto.

Because nuestra has to agree with profesora, which is a feminine singular noun.

• nuestro profesor = our male teacher
• nuestra profesora = our female teacher

Even though our in English does not change, Spanish possessives do.

Profesora is the feminine form of profesor.

• el profesor = the male teacher
• la profesora = the female teacher

So this sentence is specifically talking about a female teacher.

Spanish usually uses ser for qualities seen as more essential, characteristic, or defining, and estar for temporary states or conditions.

Here, exigente means demanding/strict, and it is being presented as part of the teacher’s character, so es is the natural choice:

• Es exigente = She is demanding / strict by nature or as a general trait.

If you said está exigente, it would sound more like she is being unusually demanding right now.

Because exigente is an adjective with the same form for masculine and feminine.

• un profesor exigente
• una profesora exigente

What can change is the number:

• un profesor exigente
• dos profesores exigentes

So in this sentence, exigente already works correctly with profesora.

Aunque means although / even though.

It introduces a contrast:

• Nuestra profesora es exigente = Our teacher is demanding
• aunque siempre corrige con paciencia y con respeto = although she always corrects with patience and respect

So the idea is: she is demanding, but at the same time she is patient and respectful when correcting.

Because the speaker is stating something as a real fact: the teacher really does always correct with patience and respect.

After aunque, Spanish can use either the indicative or the subjunctive, depending on meaning:

• indicative: when the information is presented as true or known
• subjunctive: when it is hypothetical, uncertain, or not confirmed

Here it is factual, so:

• aunque siempre corrige... = although she always corrects...

If it were uncertain, you might see subjunctive in another context.

The verb is corregir (to correct), and in the present tense it has a stem change: e → i in many forms.

So:

• yo corrijo
• tú corriges
• él/ella corrige
• nosotros corregimos
• vosotros corregís
• ellos corrigen

In this sentence, the subject is nuestra profesora, which is third person singular, so corrige is the correct form.

Because Spanish often omits subject pronouns when the verb form already makes the subject clear.

Here, corrige already tells us it is she/he/you formal, and the previous part of the sentence has already identified the subject as nuestra profesora.

So Spanish naturally says:

• Nuestra profesora es exigente, aunque siempre corrige...

Adding ella is possible, but unnecessary unless you want emphasis or contrast.

Siempre usually goes before the conjugated verb when it means always in a general sense.

So:

• siempre corrige = she always corrects

This is the most natural word order here. Spanish does allow some flexibility, but siempre corrige is the standard, neutral phrasing.

Yes, both are possible.

• con paciencia y con respeto
• con paciencia y respeto

Repeating con gives each noun a little more weight and clarity. It can sound slightly more careful or balanced. Without repeating it, the sentence is still completely correct and natural.

So here, the repetition helps emphasize both qualities separately:

• with patience
• and with respect

Because after con, Spanish often uses abstract nouns without an article when speaking in a general way.

So:

• con paciencia = patiently / with patience
• con respeto = respectfully / with respect

This is very common with abstract nouns like:

• con calma
• con cariño
• con cuidado
• con respeto

Using an article would usually change the nuance or sound less natural in this context.

It is literally with patience and with respect, but in natural English it often functions like adverbs:

• corrige con paciencia ≈ she corrects patiently
• corrige con respeto ≈ she corrects respectfully

Spanish very often uses con + noun where English might prefer an adverb.

In standard Peninsular Spanish, corrige is pronounced approximately ko-RRI-he.

A few key points:

• the rr is a strong rolled sound
• the g before e sounds like a strong throaty h
• the stress is on -ri-: co-RRI-ge

So in Spain it is roughly:

• corrige → ko-RRI-he

In Spain, paciencia is pronounced approximately pa-THYEN-thya in central/northern standard pronunciation.

Important sounds:

• ci is pronounced like th in thin in most of Spain
• the stress is on -cien-

So:

• paciencia → pa-THYEN-thya

In Latin America, that th sound is usually pronounced like s instead.

Usually demanding is the best match.

Depending on context, it can also suggest:

• strict
• high standards
• expecting a lot from students

So es exigente does not necessarily mean the teacher is mean or unfair. In this sentence, the second part makes that clear: she is demanding, but she corrects with patience and respect. That gives exigente a more positive or balanced sense.
