“Perdón por molestar” is one of the most ordinary phrases in Spanish, said before asking a small favor, interrupting someone's work, or knocking on a closed door. It carries about as much weight as “sorry to bother you” does in English. The English word it resembles carries an entirely different amount of weight, and the gap between the two is the widest on this list.
Why This Gap Is Different From the Others
What does “molestar” actually mean in Spanish?
To bother, annoy, or disturb someone in a completely everyday sense — interrupting a phone call, asking for a moment of someone's time, or making a small request. It's polite, common, and carries no serious implication at all.
Why is saying “sorry to molest you” such a big mistake in English?
Because unlike most false friends, which shift tone or category, this one shifts severity. “Molest” in English describes a serious crime, not a minor inconvenience. The sentence goes from a polite apology to something a native listener can't casually let pass.
Most false friends get a confused look and move on. This one doesn't. A native English speaker who hears “sorry to molest you” isn't confused, they're alarmed, and the conversation doesn't continue as though nothing happened. The mistake gets remembered long after the actual sentence is forgotten.
How Often the Spanish Word Actually Comes Up
Part of what makes this trap costly is frequency. “Molestar” isn’t an unusual word you reach for occasionally, it’s everyday politeness vocabulary: “perdón por molestar” when interrupting, “¿te molesta si...?” when asking permission, “no te molestes” when telling someone not to go to any trouble. A Spanish speaker might use it several times a day without it carrying any weight at all.
So this isn’t a word you can simply avoid until you’ve learned the right one. The situations that call for it come up constantly, which means you need a replacement ready rather than a warning to be careful.
What to Say Instead, by Situation
Interrupting someone
“Sorry to bother you — do you have a second?”
Same thing, more formal
“Sorry to trouble you. Is now a good time?”
Asking permission
“Do you mind if I open the window?”
Written or with someone senior
“Would it be a problem if I opened the window?”
Telling someone not to go to any trouble
“Don't worry about it, honestly.”
Declining an offer politely
“Please don't go to any trouble on my account.”
English Narrowed the Word. Spanish Didn’t.
Both words come from the same Latin root, molestare, which meant to trouble or annoy. Spanish kept that meaning intact. English carried it for centuries too, and then over the last hundred years or so the everyday sense drained away and a far graver one took its place.
That history explains why the trap is so one-sided. A Spanish speaker isn’t reaching for a strange word, they’re using the original meaning of a word English has since repurposed. The Spanish usage didn’t drift. English did.
