Both phrases are grammatically correct, but they aren’t interchangeable. According to Merriam-Webster, “sorry” can be followed by different grammatical patterns depending on timing: “sorry to bother you” is used right before or during an interruption, while “sorry for bothering you” is used after the interruption has already happened.
The Grammar Behind Both Versions
“Sorry” can be followed by either an infinitive (“to bother”) or a preposition plus a gerund (“for bothering”), and both patterns are standard English grammar. The difference comes down to timing, not correctness. This same pattern shows up in other apology and emotion-based phrases, where the infinitive form tends to describe something you’re about to do, and the “for” plus -ing form describes something already done or ongoing.
When to Use “Sorry to Bother You”
Use this version right before, or in the moment of, interrupting someone. It signals: “I know this is an interruption, and I’m doing it anyway because I need something.”
“Sorry to bother you, but do you have a minute?”
“Sorry to bother you so late at night.”
When to Use “Sorry for Bothering You”
Use this version after the interruption has already happened, often in a follow-up message, email, or when reflecting on something you already did.
“Sorry for bothering you earlier, I found the answer myself.”
“Sorry for bothering you with so many emails this week.”
Which One Sounds More Polite?
Neither is inherently more polite than the other. “Sorry to bother you” tends to sound slightly more natural in spoken, in-the-moment situations, while “sorry for bothering you” is more common in written follow-ups, like emails or messages sent afterward.
More Formal Alternatives
If you’re writing a professional email and want to avoid sounding overly apologetic, consider these alternatives:
“I hope I’m not interrupting, but…”
“Apologies for the interruption.”
“Thank you for your patience while I follow up on this.”
These options acknowledge the imposition without repeating “sorry” too often, which can come across as overly deferential in professional writing.
A Common Related Mistake
Some people mix the two grammar patterns and write “sorry to bothering you” or “sorry for bother you.” Neither of these is correct: “to” must be followed by the base verb (“bother”), and “for” must be followed by the -ing form (“bothering”).
Incorrect: “Sorry to bothering you”
Incorrect: “Sorry for bother you”
Correct: “Sorry to bother you” or “Sorry for bothering you”
Frequently Asked Questions
Is “sorry to bother you” formal or informal? It works in both contexts. It’s neutral enough for casual conversations and polite professional messages alike.
Can I use both phrases in the same message? Rarely, since it can feel repetitive, but a message like “Sorry to bother you again, I’m following up on the email I sent, sorry for the back-and-forth” works because each phrase is doing a different job.
Is one version American and the other British? No. Both are used across English-speaking regions; the difference is about timing, not geography.
