# func (10-func.com)

Short for 'function.' People say it when they mean a job or purpose something serves, or a social gathering like a party or banquet. It is casual speech, closer to 'role' or 'party' than to anything technical.

## What a model may hear
- function declaration or literal (programming languages (Go, C#, Swift, JavaScript)): Expect a code block, parameters, and a return type; may try to write or evaluate source code
- functional programming (computer science and FP libraries): Assume pure functions, immutability, and higher-order patterns; may reject side effects or mutable state
- mathematical function (mathematics and machine learning): Treat inputs as mapping deterministically to outputs; may apply formal properties like injectivity or continuity
- Azure Functions or AWS Lambda shorthand (cloud computing): Expect serverless deployment configuration, triggers, and bindings
- FUNC instruction or register (CPU architecture and assembly): Interpret as a low-level operation or hardware register name

## Where people and models part ways
- Says: "What's the func of this team?"
  Means: What is this team's purpose or role?
  May be taken as: The model may explain team structure as a software function or generate code for a team management system
  Say instead: "What is the purpose or role of this team?"
- Says: "I need to plan a func for Friday"
  Means: I am organizing a social event or party
  May be taken as: The model may generate serverless function deployment schedules or event handler code
  Say instead: "I need to plan a social event or party for Friday"
- Says: "Make this a func"
  Means: Turn this into a reusable routine or habit
  May be taken as: The model may refactor prose into a programming function or demand syntax like parentheses and braces
  Say instead: "Make this into a reusable step-by-step routine"
- Says: "The func isn't working"
  Means: The purpose or social event is failing
  May be taken as: The model may debug code, ask for stack traces, or suggest programming fixes
  Say instead: "The purpose isn't being served, or the event isn't going well"

## Tips
- Say 'purpose,' 'role,' or 'job' when you mean what something is for.
- Say 'party,' 'event,' or 'gathering' when you mean a social occasion.
- If you want code, add a language name like 'in Python' or 'in Go.'
- Avoid 'func' alone when describing business processes or human activities.
- If a model replies with code you did not want, restate using 'purpose' or 'step-by-step process.'

## Often confused with
- function: the full word; models treat it identically in code contexts
- fun: enjoyment; models rarely confuse it with programming
- def: Python keyword for defining functions; more clearly technical
- lambda: anonymous function; models always read it as code
- proc: procedure; similar shorthand but more associated with SQL or Pascal
- method: function attached to an object; implies object-oriented context
