# rel (0-rel.org)

Short for relationship. People say it to mean how two people connect, or how things relate to each other. It can also mean a relative, like family.

## What a model may hear
- HTML rel attribute (web development): assume the user wants to specify link semantics like stylesheet, noopener, or noreferrer
- relation in databases (SQL and relational algebra): treat the input as a table or set of tuples to query or join
- relative instruction in assembly (low-level programming): interpret the term as a relative address or offset for jumps and branches
- release build or version (software packaging): assume the user means a compiled release artifact, not a debug build
- relativistic physics constant (physics and astronomy): invoke formulas for special or general relativity

## Where people and models part ways
- Says: "fix my rel"
  Means: help with my romantic relationship
  May be taken as: debug HTML link attributes or database foreign keys
  Say instead: "help me with my romantic relationship"
- Says: "rel is broken"
  Means: my family member is unwell
  May be taken as: diagnose a broken database relation or failed software release
  Say instead: "my relative is sick and I need advice"
- Says: "add rel to the page"
  Means: write about relationships on the website
  May be taken as: insert HTML rel attributes into every link element
  Say instead: "write content about personal relationships for the website"
- Says: "calculate rel"
  Means: figure out how two things are connected
  May be taken as: run a relativistic physics calculation or SQL query
  Say instead: "explain how these two concepts are connected"

## Tips
- Say relationship in full when you mean people.
- Say relative when you mean family.
- Add HTML before rel if you mean the link attribute.
- Say database relation if you mean tables.
- Say release if you mean a software version.

## Often confused with
- ref: means reference, not relationship
- rev: means reverse or revision, opposite direction
- href: the actual link URL, not its relationship type
- sql: the query language, not the concept of relations
- relativity: Einstein's physics, not personal connections
- relay: a switch or message forwarder, not a bond
