Cue

Simple meaning

A cue is a signal that tells you — or your brain — that it is time to do something.

Detailed meaning

A cue is the starting signal. It is the thing that sets everything else in motion.

In theatre and film, a cue is the signal that tells an actor to speak, a technician to change the lighting, or a musician to play. Everyone waits for their cue.

In habit science, a cue is the first step in the habit loop: cue → craving → response → reward

The cue triggers a craving. The craving drives a response. The response delivers a reward. Without the cue, the habit loop does not start.

There are five common types of habit cues:

1. Time — "It's 7 a.m." → you make coffee
2. Location — "I'm in the kitchen" → you snack
3. Emotional state — "I feel stressed" → you check your phone
4. Other people — "She's opening her laptop" → you open yours
5. Preceding action — "I just finished lunch" → you go for a walk

Word forms:

• Cue (noun) — the signal: "The alarm is her morning cue."
• Cue (verb) — to signal something: "The music cued the performers to enter."
• Cued (past tense) — "The habit was cued by the smell of coffee."

Common phrases:

• "Take your cue from…" — to follow someone's lead: "Take your cue from the most experienced person in the room."
• "Cue the music" — signal the music to begin (also used humorously when something predictable happens)
• "Environmental cue" — a physical trigger in the surroundings

Where to use it

• Habits and behaviour design — "Placing your running shoes by the door is an environmental cue to exercise."
• Theatre and media — "The director gave the cue for the final scene to begin."
• Everyday conversation — "That look was my cue to stop talking."

Where not to use it

Do not confuse cue with queue. They sound identical but mean different things. A cue is a signal or trigger. A queue is a line of people or items waiting for something. This is one of the most common spelling mistakes in English.

5 example sentences

1. The alarm was not just a wake-up tool — it was a cue that triggered her entire morning routine automatically.
2. He noticed that stress was his cue to reach for his phone — not because he needed information, but because the phone had become his comfort response.
3. She designed her workspace with deliberate cues: a candle lit meant deep work time; a candle unlit meant open time for emails and calls.
4. In the film industry, the director says "action" — a single cue that sets forty people in motion simultaneously.
5. "Take your cue from the most experienced person in the room," the mentor advised. "Watch how they handle pressure before you decide how to respond."

Memory trick

A short story to remember it

For years, she snacked every time she sat on the sofa.

She thought she was hungry. But she realised one evening that she had eaten a full dinner twenty minutes earlier. She was not hungry. She was responding to a cue.

The sofa was the cue. The moment she sat down, her brain said: snack time.

She made one change. She put a book on the sofa cushion instead of snacks on the side table.

The cue stayed — sitting on the sofa. But the response changed. The book was now the first thing she reached for.

Same cue. New response.

"You do not need to destroy a habit. You need to interrupt the cue — or redirect what follows it."

Summary

A cue is a signal that tells the brain it is time to act — the first step in the habit loop (cue → craving → response → reward). Cues can be time-based, location-based, emotional, social, or action-based. In theatre and film, a cue is the signal that starts the next action. Common phrases: "take your cue from," "environmental cue." Do not confuse cue (signal) with queue (a waiting line) — they sound the same but are different words entirely.
