# id (10-id.com)

People say "id" to mean a name tag or badge that proves who you are. They also use it for any number or card that identifies them, like a driver's license or a student ID.

## What a model may hear
- primary key (databases): Treat it as a unique row identifier, often auto-incremented, and may write SQL queries using it as a join or lookup key
- Freudian id (psychology): Interpret it as the instinctual part of the psyche, possibly generating content about desire and unconscious drives
- HTML id attribute (web development): Assume it refers to a unique element selector in CSS or JavaScript, and may write code targeting #id
- process or user ID (operating systems): Read it as a numeric PID or UID, and may discuss permissions, process management, or system calls
- identity function (mathematics and functional programming): Interpret it as f(x) = x, a function that returns its input unchanged

## Where people and models part ways
- Says: "I lost my id"
  Means: They cannot find their physical identification card
  May be taken as: The model may think a database primary key is missing or corrupted
  Say instead: "I lost my physical ID card"
- Says: "Check my id"
  Means: Please verify who I am
  May be taken as: The model may inspect a user ID number or HTML element ID instead of asking for verification
  Say instead: "Please verify my identity"
- Says: "I need a new id"
  Means: They want a new identification document
  May be taken as: The model may generate a new database key or UUID instead of explaining how to get a government ID
  Say instead: "I need to get a new government-issued ID"
- Says: "The id is wrong"
  Means: Their name or information on their card is incorrect
  May be taken as: The model may debug a database schema or code bug involving identifier mismatch
  Say instead: "My personal information on my ID card is wrong"

## Tips
- Say 'government ID' or 'photo ID' when you mean a physical card
- Say 'database ID' or 'record ID' when you mean a number in a system
- Say 'HTML id' or 'CSS id' when you mean a web element identifier
- Say 'user ID' or 'account ID' when you mean a login identifier
- Say 'Freudian id' explicitly if you mean the psychological concept

## Often confused with
- ego: the conscious self, not an identifier
- tag: a label, not necessarily unique
- key: opens locks or encrypts, not just names
- name: human-readable, not always unique
- token: a temporary credential, not permanent identity
- UUID: a specific long random identifier format
