## What people usually mean

The Moon is Earth's natural satellite, the bright object in the night sky. People speak of moonlight, moon phases, and landing on the moon. It evokes romance, exploration, and the passage of time.

## Senses you may read into it

Use one of these only when the conversation is already in that field.

- lunar body (astronomy, general knowledge): treat as Earth's satellite, discuss missions, tides, or orbital mechanics
- Moon script (programming languages): assume a compiled-to-Lua language for game engines, especially Love2D
- moon phase algorithm (date/calendar libraries): calculate illumination, phase names, or rise/set times for a given date
- Moon OS or Moon browser (obscure or deprecated software): retrieve outdated documentation or conflate with similarly named projects
- to moon (slang) (internet culture, finance): interpret as rapid price rise ('to the moon') or as crude gesture

## When a person says

- "Draw me the moon"
  They mean: a picture of Earth's moon in the sky
  Avoid: generate MoonScript code or a lunar phase diagram
  Read it as: "Draw a picture of Earth's moon in the night sky"

  Avoid: explain cryptocurrency investment strategies
  Read it as: "How did NASA missions reach Earth's moon?"

- "Write a moon program"
  They mean: a program about the moon
  Avoid: write code in MoonScript language
  Read it as: "Write a program that displays information about Earth's moon"

## Words it is confused with
