Learn Hardcore Spanish (Spain): Agradezco mucho cuando mis amigos corrigen mis errores con respeto. - I’m very grateful when my friends correct my mistakes respectfully.

In English we’d usually say “I really appreciate it when …”. Why does the Spanish sentence start with Agradezco mucho instead of something like Lo agradezco mucho?

In Spanish you can:

include the direct object pronoun: Lo agradezco mucho.
or leave it implied: Agradezco mucho cuando…

In Agradezco mucho cuando mis amigos corrigen…, the thing being appreciated is the whole action described by the cuando clause, so it’s clear from context and the lo is not necessary.

Both are correct:

Agradezco mucho cuando mis amigos corrigen mis errores con respeto.
Lo agradezco mucho cuando mis amigos corrigen mis errores con respeto.

The version without lo sounds very natural and is slightly lighter / less repetitive in everyday speech.

Why is it Agradezco mucho and not Estoy muy agradecido? Do they mean the same thing?

They are close in meaning but not identical:

Agradezco mucho… = I really appreciate / I greatly appreciate…
- Verb-focused, sounds a bit more active, closer to “I appreciate”.
Estoy muy agradecido cuando… = I’m very grateful when…
- Adjective-focused, describes your state of being grateful.

Both could be used, but the original sentence with Agradezco mucho sounds very natural when introducing what you appreciate in general or habitually.

Example alternatives:

Agradezco mucho que mis amigos corrijan mis errores con respeto.
Estoy muy agradecido a mis amigos cuando corrigen mis errores con respeto.

Why is it cuando mis amigos corrigen and not cuando mis amigos corrijan? I thought cuando often triggers the subjunctive.

Cuando only triggers the subjunctive in certain situations, mainly when referring to future / hypothetical actions, often after a main clause in the future or with commands.

Here, cuando mis amigos corrigen describes a habitual, real situation in the present, so Spanish uses the indicative:

Agradezco mucho cuando mis amigos corrigen mis errores…
= I appreciate it a lot whenever my friends correct my mistakes (as a general rule).

Compare:

Agradeceré mucho que mis amigos corrijan mis errores.
(future, hypothetical → subjunctive corrijan)
Siempre agradezco cuando mis amigos corrigen mis errores.
(habitual, real → indicative corrigen)

So here corrigen (indicative) is correct and natural.

Could I say Agradezco mucho que mis amigos corrijan mis errores con respeto instead? What’s the difference?

Yes, that’s completely correct, but the structure changes slightly:

Agradezco mucho cuando mis amigos corrigen mis errores…
Emphasizes whenever they do this (habitually, in general).
Agradezco mucho que mis amigos corrijan mis errores…
Emphasizes the fact that they do it at all, as a situation you’re grateful for. The verb corrijan is in the subjunctive because it’s inside a que-clause of influence/emotion (agradecer que + subjunctive is standard).

Both are natural; the nuance is very small. The que + subjunctive version sounds a bit more like “I’m grateful for the fact that my friends correct my mistakes respectfully.”

Why is it mis amigos corrigen mis errores and not me corrigen mis errores or just me corrigen?

All of these are possible, but they focus on different things:

mis amigos corrigen mis errores
- Explicit subject (mis amigos) and explicit object (mis errores).
- Very clear and neutral: my friends correct my mistakes.
mis amigos me corrigen
- Emphasis on me as the person being corrected; the “my mistakes” part is understood from context.
mis amigos me corrigen mis errores
- Grammatically possible, but often feels a bit heavy or redundant.
- In many contexts, speakers would just say me corrigen or corrigen mis errores rather than both me and mis errores.

The original sentence chooses the clearest, most explicit version: mis amigos corrigen mis errores.

Why is it con respeto and not something like respetuosamente or de manera respetuosa?

All three exist, but con respeto is:

shorter,
more common in everyday speech,
very natural in Spain.

Compare:

con respeto = with respect (simple, neutral, colloquial and standard)
de manera respetuosa / de forma respetuosa = in a respectful way (a bit more formal / explanatory)
respetuosamente = respectfully (sounds very formal or fixed, often used in letters/emails: Atentamente / Respetuosamente)

In this context, con respeto is by far the most natural choice.

Where should mucho go? Could I say Cuando mis amigos corrigen mis errores con respeto, agradezco mucho or Agradezco cuando mis amigos corrigen mis errores con mucho respeto?

Spanish word order is flexible, and these are all possible with slight nuance changes:

Agradezco mucho cuando mis amigos corrigen mis errores con respeto.
- Most neutral: mucho directly modifies agradezco.
Cuando mis amigos corrigen mis errores con respeto, lo agradezco mucho.
- Starting with the cuando-clause adds emphasis to the condition.
Agradezco cuando mis amigos corrigen mis errores con mucho respeto.
- Here mucho now intensifies respeto, not agradezco.
- Means: I appreciate it when they correct my mistakes with *a lot of respect.*

So:

Agradezco mucho = I appreciate it a lot.
con mucho respeto = with a lot of respect.

Why is Agradezco in the simple present and not something like Estoy agradeciendo?

Spanish uses the simple present much more than English to express:

general truths,
habits,
attitudes and mental states.

Agradezco mucho cuando… describes a general attitude, not an action happening right now, so the simple present is perfect.

Estoy agradeciendo is almost never used; it would sound strange in most contexts. For ongoing appreciation, you’d still use simple present:

Ahora mismo agradezco mucho tu ayuda.
(Not estoy agradeciendo.)

Is errores the only word I can use? What about fallos or equivocaciones?

You could use others, with slightly different nuances:

errores – the most neutral and general: mistakes, errors.
fallos – common in Spain; often mistakes / faults / flaws.
equivocaciones – focuses a bit more on being wrong / misunderstandings.

All of these would be understood:

…corrigen mis errores con respeto.
…corrigen mis fallos con respeto.
…corrigen mis equivocaciones con respeto.

Errores is the standard, textbook-friendly choice.

Do I need mis before amigos and errores? Could I say Agradezco mucho cuando amigos corrigen errores con respeto?

Spanish normally uses possessive adjectives where English might omit my:

mis amigos = my friends
mis errores = my mistakes

If you drop mis, it sounds like you’re talking about friends and errors in general, not specifically yours. That would be strange here, because you are clearly talking about your friends and your mistakes.

So in this sentence, mis is natural and expected:
Agradezco mucho cuando mis amigos corrigen mis errores con respeto.

Is this sentence specifically “Spain Spanish”, or would it also sound natural in Latin America?

The sentence is fully standard and would be understood and accepted anywhere in the Spanish-speaking world:

Agradezco mucho cuando mis amigos corrigen mis errores con respeto.

There’s nothing particularly regional (no slang, no peninsular-only expression). A Latin American speaker might say exactly the same sentence. Any differences would be more about accent or preferred synonyms, not grammar.
