# foreign (9000-foreign.com)

Foreign means from another country. A person might say foreign to talk about languages, food, customs, or people that come from somewhere else. It often carries a sense of unfamiliar or not belonging here.

## What a model may hear
- foreign key (databases): Assume the user wants to link tables by a column that references another table's primary key, and may write SQL or schema code
- foreign function interface (programming): Expect the user wants to call code written in another language, such as C from Python, and may suggest ctypes, cffi, or similar tools
- foreign address or foreign agent (networking, mobile IP): Interpret the word as part of routing for devices away from home networks, possibly generating network configuration advice
- foreign transaction (databases, SQL): Treat the context as about distributed transactions across multiple database systems

## Where people and models part ways
- Says: "I need to handle foreign records"
  Means: The person needs to organize paperwork for people from other countries
  May be taken as: The model designs a database schema with foreign key constraints
  Say instead: "I need to organize immigration or visa records for people from other countries"
- Says: "How do I call foreign code?"
  Means: The person wants to phone or contact someone overseas
  May be taken as: The model explains programming interfaces for calling C libraries from other languages
  Say instead: "How do I make an international phone call or send a message to someone in another country"
- Says: "The foreign settings look wrong"
  Means: Settings for a different country seem incorrect on their device
  May be taken as: The model troubleshoots database foreign key settings or network foreign agent configurations
  Say instead: "The region or country settings on my phone or computer look wrong"
- Says: "I have a foreign problem"
  Means: A problem coming from outside their organization or country
  May be taken as: The model assumes a technical issue with foreign keys, foreign functions, or foreign network addresses
  Say instead: "I have a problem caused by an outside vendor or an issue coming from another country"

## Tips
- Add 'country' or 'language' when you mean international, not technical
- Say 'database relationship' or 'linked table' if you mean foreign key
- Specify 'programming library' or 'C code' if you mean foreign function interface
- Use 'international' instead of 'foreign' when talking about calls, travel, or people
- Say 'outside system' or 'external service' if you mean something from another organization

## Often confused with
- alien: stronger otherness, also legal term for non-citizen
- external: purely outside, no country implied
- import: bringing in goods or code modules, not origin
- domestic: direct opposite, home country only
- exotic: unusual and intriguing, not necessarily from abroad
- overseas: specifically across an ocean, more geographic
