Apologizing in English: you already say sorry, you just skip the second sentence
Spanish speakers say sorry in English almost as often as natives. What gets lost is the offer to fix it. Lines for each situation, and for accepting apologies.

You hand your London roommate back the book she lent you, with a coffee stain on the cover. You say "Sorry," she answers "It's fine" with half a smile, and the moment goes strange. You apologized, in English, right away. Something was missing, and it wasn't the word.
An apology in English has two parts: the word, and what you offer next. Spanish-speaking learners already have the first part down. In Montserrat Mir's study of learners from Spain, 81.9% of their English responses included a sorry, against 88.4% for Americans. The real gap is the second part: the learners offered to fix the damage 28% of the time, the native speakers 62%. The formula that works is short: apology + repair, with really when the damage is serious. And when someone apologizes to you, a short reply is all it takes.
You don't lack the sorry. You lack the offer to fix it
The stereotype says Spanish speakers don't apologize in English, and the data says otherwise. Mir compared 29 English learners in Barcelona with 29 American students in Illinois across eight situations: breaking someone's glasses, showing up late to a pickup basketball game, bumping into an older woman on the street. Speaking Spanish, the Spaniards used an apology formula in 67.2% of their responses. In English they rose to 81.9%, close to the natives. And 65.2% of those learners believed English speakers apologize more, so they compensated.

What didn't carry over was the repair: I'll pay for it, Let me fix it, I'll get you a new one. The learners offered it in 28% of situations, the Americans in 62%. Mir herself points at how apologies get taught: "there seems to exist an emphasis on teaching apologetic expressions (e.g., "I'm sorry") as the only strategy for apologizing in English". If I'm sorry is all you learned in class, it makes sense that your apology stops there.
The pattern isn't only Spain's. Marisa Cordella compared Chileans and Australians and found something similar: the Chileans used fewer explicit apologies and gave more explanations. Keep the scope in mind: both studies are role-plays with small groups, not recordings of real life, but they point the same way.
Sorry isn't "lo siento": it does more jobs
Lo siento carries more weight than sorry. A study by Marianna Chodorowska-Pilch shows the problem from the other side: English speakers learning Spanish overuse lo siento, because they move every use of sorry onto an expression that is narrower in Spanish. If sorry sounds like lo siento to you, you'll save it for serious moments and come up short on the small ones.
In English, sorry lives mostly in the small moments. Mats Deutschmann analyzed more than 3,000 real apologies in the British National Corpus, and in his thesis sorry appears in 59% of explicit apologies, and half of the examples work as a cushion, said before something rather than after an offense: Sorry, can I just… before a request, Sorry, but… before disagreeing, Sorry? to ask someone to repeat. About those repetition requests, Deutschmann writes that "they have become so conventionalised in English that their mere utterance is a request in itself". That sorry confesses nothing. It clears the way.

Four situations, four cards
Bumping into someone on the street or the subway. "Oh, sorry!" is enough. Excuse me works too: the Cambridge Dictionary lists it for apologizing for something you did by accident, as well as for getting someone's attention or asking to get past. As a rule of thumb, excuse me comes before you bother someone and sorry comes after; in a bump, either works. Don't be surprised if, in England, the person you bumped apologizes to you: according to YouGov, 36% of Britons would say sorry if someone else bumped into them, against 24% of Americans. The anthropologist Kate Fox bumped into hundreds of people on purpose, and around 80% of the English apologized to her. Comparing them with tourists from other countries, Fox writes: "Only the Japanese seemed to have anything even approaching the English sorry-reflex." It was an informal experiment, not a published study, but it helps you read the scene: that sorry admits no guilt.
You're late. "Sorry I'm late. The train was delayed." One reason, then stop. In Mir's data, the Spaniards gave more explanations than the Americans precisely for minor offenses (40.5% vs. 33.6%). In English, the long traffic story sounds more like an excuse than an apology.
You break or stain something. This is where the second sentence comes in: "I'm really sorry. I'll get you a new copy." or "I'm so sorry. Let me pay for the cleaning." Pick the adverb carefully. According to the summary by CARLA at the University of Minnesota, in American English really signals more regret and very more etiquette, so I'm very sorry can sound like a formality. If someone got hurt, add a question: "I'm really sorry. Are you OK?" Mir measured that intensity: for serious offenses, 47.7% of the natives intensified their apology, against 20.7% of the learners.
A mistake at work. Own it and fix it in the same breath: "Sorry, that was my mistake. I've sent the corrected file." No drama, no blaming the system. And don't be thrown if your boss apologizes to you: in Deutschmann's corpus, people with more power apologized far more to people with less power than the other way around.
Does the second sentence come out without thinking, or do you stop at sorry and an awkward silence? With Tabla you say phrases out loud until they come on their own, so Let me fix it arrives right behind the sorry, not ten seconds late.
When someone apologizes to you
Accepting an apology in English is shorter than in Spanish. The word-for-word version of no pasa nada, "nothing happens," leaves the other person unsure whether you've forgiven them. The natural replies are three: "No worries," "That's OK," and "Don't worry about it." The Cambridge Dictionary uses exactly this example: "Oh, I'm sorry I got your name wrong!" "No worries." If the damage was real and they offer to fix it, accept or decline plainly: "Thanks, that would be great" or "Honestly, don't worry about it."
You spill coffee on a coworker's backpack at the office. What do you say in English, in two sentences?
Something like "Oh no, I'm really sorry! Let me get some paper towels, and I'll pay for the cleaning." The first sentence uses really, not very, because the damage is real. The second offers to fix it, which is exactly the part learners' apologies lose most often.
Next time you say sorry, don't stop there: add the second sentence.
Try this today: say "I'm really sorry. Let me fix it." out loud three times, then "No worries, don't worry about it," so the full apology and the reply come out as fast as the sorry does.
