A stack of AI-related terms moved out of engineering teams and into ordinary office conversation in under two years, faster than most vocabulary shifts in modern workplace English. People who learned business English even five years ago now hit a real gap in meetings: not grammar, not fluency, just missing words that didn't exist yet when they studied. None of this shows up in standard textbooks so far, which means the only place to actually pick it up is the conversation itself.
Five Terms Now Common in Ordinary Meetings
“Prompt engineering”
Everyday workWriting and refining the instructions you give an AI tool so it returns a better result. It used to be a specialist's job title; now it's a skill anyone mentions in passing.
"I spent twenty minutes on prompt engineering before it gave me something usable."
“Human-in-the-loop”
Process talkA process where a person checks or approves an AI's output before it moves forward. Used to describe a workflow, not to explain a technical setup.
"We're keeping a human in the loop on anything client-facing for now."
“Hallucination”
Quick correctionWhen an AI tool states something false with total confidence. The word kept its old meaning too, so context decides which one a speaker means.
"Double-check that figure, could just be a hallucination."
“Agentic”
Tool descriptionDescribes a tool that takes multiple steps on its own toward a goal, rather than answering one prompt and stopping. Increasingly used as a plain adjective.
"It's fully agentic now, it books the meeting and sends the recap."
“Context window”
Casual complaintThe amount of earlier conversation or text an AI tool can still 'remember' while working. Non-technical staff now use it loosely to mean attention span.
"Past a certain point it just falls out of the context window and forgets the brief."
The Same Word Can Mean Two Different Things Now
The tricky part isn't always the new words. It's the old ones that quietly picked up a second meaning. "Hallucination" is the clearest example: it still means what it always meant, and it now also means an AI making something up with total confidence. The only way to tell which one a colleague means is context, and context only works if you're listening closely enough to catch the surrounding sentence, not just the one keyword.
ONE WORD, TWO MEANINGS
Nobody warns you that 'hallucination' now has a second definition. You just have to catch it from context, live, in the room.
