Come across has two meanings in professional English that have nothing to do with each other, which is exactly why it confuses learners. You have to rely on context, not the words themselves, to know which one is meant.
- To find or encounter something by chance, without looking for it specifically.
- To give a particular impression to other people (also written as come across as).
Sense 1: finding something by chance
Used this way, come across means you found something — a document, an error, a person — without deliberately searching for it.
"I came across an old contract while cleaning up the shared drive."
"While reviewing the logs, she came across a bug nobody had reported."
This sense is close to stumble upon or find, but it carries a specific flavor: the discovery was incidental, a side effect of doing something else.
"I came across your name in an old thread and thought I'd reach out."
Sense 2: giving an impression
Used with as, come across describes how someone is perceived by others — often not how they intended to be perceived.
"He didn't mean to sound dismissive, but he came across as rude in the email."
"Try to come across as confident, not defensive, when you present the numbers."
"The proposal came across as more expensive than it actually is, because the pricing section was buried."
Notice the structure: come across as + adjective/noun. This is the version people usually need for feedback conversations — describing a gap between intent and perception.

The reliable signal is the word as. If as follows, you're almost always in the "impression" sense. If there's no as, and instead a direct object (a thing or person found), you're in the "chance discovery" sense.
"I came across a great article." (found by chance — no as)
"The article came across as biased." (impression — has as)
If you're ever unsure which one you mean, ask whether you're describing something you found or something that seemed a certain way to someone. That question resolves almost every ambiguous case.
Common mistakes
Mistake 1: Dropping "as" in the impression sense.
Wrong:
"He came across rude in the meeting."
Correct:
"He came across as rude in the meeting."
Mistake 2: Adding "as" in the discovery sense, which sounds unnatural.
Wrong:
"I came across as an old file while cleaning up the drive."
Correct:
"I came across an old file while cleaning up the drive."
Mistake 3: Confusing "come across as" with "seem like" in formal writing.
Both work, but come across as usually implies an impression formed through behavior or tone, while seem can be based on almost anything, including facts. In feedback conversations, come across as is often the more precise and diplomatic choice because it frames the issue as perception, not fixed fact.
Practice scenarios
Practice using come across in situations like:
- mentioning something you found unexpectedly while doing unrelated work
- giving a colleague feedback about how their tone landed in a meeting or email
- describing how a proposal or pitch was perceived by a client
- softening criticism by framing it as an impression rather than a judgment
Useful practice phrases:
- "I came across [something] while..."
- "That might come across as..."
- "I don't think that's how you meant it, but it came across as..."
- "How do you think the pitch came across?"
