Can I say "I'm blocked"?

Yes — it's the most natural way to say it. "I'm blocked on the API review" is exactly how a native-speaking engineer would phrase it in a standup or on Slack.

What is a blocker in Agile or Scrum?

In Agile/Scrum, a blocker is anything preventing a team member from completing a task in the current sprint. Standups exist partly so blockers get raised early, before they delay the whole sprint.

What's the difference between "blocked" and "stuck"?

"Blocked" points to an external cause — you're waiting on someone or something else. "Stuck" is more personal and vague — you might be stuck because you don't know how to solve something, with no one else involved.

Is "blocker" formal or informal English?

It's informal but standard in tech workplaces — safe for Slack, standups, and tickets. In more formal written status reports, "blocking issue" is the safer alternative.

Can I use "blocker" in a job interview?

Yes. It's common and expected when describing past work — e.g. "the main blocker was that we didn't have access to production logs." It reads as precise, not casual.

Do both American and British engineers use this word?

Yes — "blocker" is standard tech-industry English on both sides of the Atlantic, largely because it comes from software culture (Agile, Jira, GitHub) rather than from either dialect specifically.

Don't say this

✕I have blocker.

✓I have a blocker.— "blocker" is countable, it needs "a"

✓I'm blocked.— you use the adjective "blocked", not the noun

✕This task block me.

✓This task is blocking me.— needs "is" + the -ing form
