Thanks, Apologies, and Natural Responses: correct answers
Jump to answers ↓The Grammar of Gratitude and Regret
When we thank someone or apologize for an action, English relies heavily on prepositions followed by gerunds (the -ing form of a verb). The most important preposition for both of these situations is for.
If you want to mention the specific action you are thankful or sorry about, use for + verb-ing.
✅ Thank you so much for bringing these beautiful flowers! ❌ Thank you so much to bring these beautiful flowers!
✅ I sincerely apologize for missing the presentation this morning. ❌ I sincerely apologize for miss the presentation this morning.
Learners often try to use the infinitive (to bring, to miss) because it translates directly from their native language. However, in English, prepositions like for, about, and on must be followed by a noun or a gerund.
Prepositions with People vs. Actions
The prepositions change depending on whether you are talking about the action or the person you are speaking to.
- Apologize to [person] for [action]: "I need to apologize to Sarah for eating her yogurt."
- Grateful to [person] for [action]: "I am so grateful to you for stepping in to help."
A common fixed expression when you want to fix a mistake you made is make it up to [person]: "I'm so sorry I shrunk your sweater in the wash! How can I make it up to you?"
Sounding Natural: Responding to Thanks
While "You're welcome" is always grammatically correct, native speakers rarely use it in casual, everyday situations among friends or colleagues. Using more natural phrases makes your conversational English flow much better.
If a friend thanks you for helping them carry a heavy sofa, try these casual responses instead:
- "No worries at all!"
- "Anytime!"
- "Don't mention it."
Avoid overly formal or literal translations of phrases from your native language. ✅ "No worries. Just let me know if you need more help." ❌ "I am very welcoming. Just let me know if you need more help."
Sounding Natural: Responding to Apologies
When someone makes a minor mistake—like a barista spilling a tiny drop of milk on your table—they might apologize profusely. Your goal in responding is to reassure them that it isn't a big deal.
Great ways to accept a minor apology include:
- "That's completely fine."
- "Don't worry about it."
- "No harm done!"
Notice that No worries is an incredibly versatile phrase. You can use it to reply to a "Thank you" (Thanks for the coffee! / No worries!) AND to reply to a minor apology (Sorry I'm late! / No worries!).
Common Error: A frequent mistake learners make is using language that is entirely too dramatic or formal for small, everyday accidents.
✅ "Oh, don't worry about it at all!" ❌ "You are forgiven."
Saying "You are forgiven" for a tiny spilled drop of coffee sounds like a king speaking to a servant, or a priest offering absolution. Stick to casual phrases like "No harm done" to keep the interaction friendly and polite.
Correct answers
Question 1
Complete the email to a colleague about a missed meeting.
I sincerely apologize _____ your presentation this morning. My train was delayed by over an hour!
The correct answer is for missing.
When giving a reason for an apology, we use the preposition for followed by a noun or a gerund (an -ing verb). Using the infinitive ("to miss") is a common mistake.
Question 2
Complete this friendly cafe encounter by dragging the correct words into the blanks.
Alex: "I'm so sorry for keeping you waiting!"
Sam: "No worries, I was just enjoying my coffee."
Alex: "Thanks for being so understanding. My dog decided to chase a squirrel!"
Sam: "Don't mention it! We've all been there."
Alex: "I'm so sorry for keeping you waiting!"
We use for + gerund (-ing) to apologize for an action. ("Sorry to keep you waiting" is also correct, but "to keeping" is grammatically incorrect.)
Sam: "No worries, I was just enjoying my coffee."
"No worries" is a very common, natural spoken expression used to respond to an apology.
Alex: "Thanks for being so understanding. My dog decided to chase a squirrel!"
After "being", we need the adjective form understanding, which describes someone who is sympathetic and forgiving.
Sam: "Don't mention it! We've all been there."
"Don't mention it" is a fixed expression used as a polite and friendly response to someone thanking you.
Question 3
Help the party host write a quick thank-you message to a guest.
Thank you so much _____ such a beautiful bouquet of flowers! They look perfect on the dining table.
The correct answer is for bringing.
After the phrase thank you, we use the preposition for to introduce the reason we are grateful. If a verb follows a preposition, it must be in the gerund (-ing) form.
Question 4
The correct answers are No worries at all!, Anytime!, and Don't mention it.
In spoken English, we rarely say "You are welcome" among close friends because it can sound a bit formal. Phrases like "Anytime!" or "No worries" are much more natural!
Note: While "Please" translates directly to "You're welcome" in some languages (like German or Italian), it is not used this way in English.
Question 5
Help the clumsy roommate complete this awkward text message exchange by dragging the correct words into the blanks.
Roommate 1: "I sincerely apologize for eating your fancy Greek yogurt. I thought it was mine!"
Roommate 2: "Oh, don't worry about it. It was past its expiration date anyway!"
Roommate 1: "Phew! I really appreciate your honesty... and your old yogurt."
Roommate 1: "I sincerely apologize for eating your fancy Greek yogurt. I thought it was mine!"
We use the preposition for after the verb "apologize" when referring to an action, usually followed by a gerund (-ing form).
Roommate 2: "Oh, don't worry about it. It was past its expiration date anyway!"
The fixed phrase is "worry about something." It is a very common and natural way to dismiss a minor apology.
Roommate 1: "Phew! I really appreciate your honesty... and your old yogurt."
We say "I appreciate [something]" to express gratitude. We cannot say "I thank your honesty" (we thank people, not things), and "grateful" requires the verb "to be" ("I am grateful for...").
Question 6
Roommate: "I want to apologize for shrinking your favorite sweater in the wash! How can I ever make it up to you?"
Friend: "Oh, please don't worry about it. It was getting old anyway! No harm done, seriously!"
apologize for: We use the preposition "for" after "apologize" when followed by an action (a gerund, like shrinking).
make it up to (someone): A fixed expression meaning to do something good for someone you have wronged.
worry about: The correct preposition to use with the verb "worry" is "about."
no harm done: A common spoken idiom used to accept an apology and reassure the person that their mistake didn't cause any real damage.
Question 7
The correct answers are Don't worry about it at all!, That's completely fine., and No harm done!
When someone apologizes for a minor accident, native speakers use fixed phrases to show that they are not upset.
"You are forgiven" sounds overly dramatic (like a king speaking to a servant!), and "It is nothing to worry" is grammatically incomplete (it should be "It is nothing to worry about").
Question 8
Cat owner: "I can't thank you enough for covering my shift yesterday. I am so grateful to you for stepping in when my cat got stuck on the roof!"
Coworker: "Not at all! I was happy to help. Any time, just let me know if Sir Fluffington decides to go mountaineering again!"
can't thank you enough: A strong, natural fixed expression used to show deep appreciation.
grateful to: You are grateful to a person for an action.
not at all: A polite and very common fixed response to someone thanking you.
any time: A friendly, casual response meaning "I would gladly help you again whenever you need it."
Question 9
Choose the most natural spoken response to complete the conversation between two friends.
Sarah: "Thanks so much for helping me move this heavy sofa!"
John: "_____. Just let me know if you need a hand with the armchair."
The correct answer is No worries.
No worries is a very common and natural way to respond to "thank you" in friendly, spoken English.
- Never mind is used to say "forget it" or "it's not important," not to reply to thanks.
- I beg your pardon is formal and used to ask someone to repeat themselves.
- It does not matter sounds dismissive and mildly rude in this context.
Question 10
The correct answers are I apologize for missing the start of class., I am so sorry for being late today., and Please forgive me for arriving late.
When apologizing for an action, we use the preposition for followed by a gerund (an -ing verb).
For example: "sorry for being late" or "apologize for missing class." Using "to" + infinitive or the preposition "of" is grammatically incorrect in these fixed expressions.
