# else (10-else.us)

Else means what happens when nothing else fits. It is the other option, the backup plan, the catch-all. People say "or else" to mean "otherwise" or "if not."

## What a model may hear
- fallback branch (programming (if/else)): execute the else block when all prior conditions are false
- alternative constructor (functional languages (Haskell, Rust)): treat else as mandatory pairing with if, or as part of expression syntax
- error state (shell scripting): route to an else clause on command failure in some constructs
- exhaustiveness check (type systems and compilers): flag missing else as incomplete pattern matching or non-exhaustive condition

## Where people and models part ways
- Says: "What else can you do?"
  Means: Give me more options or alternatives
  May be taken as: Interpret as request to enter an else branch or handle an error condition
  Say instead: "What other options do I have?"
- Says: "Or else what?"
  Means: What happens if I don't?
  May be taken as: Parse as malformed conditional expecting a code block, or as threat detection
  Say instead: "What are the consequences if I don't?"
- Says: "Nothing else matters"
  Means: Only this one thing is important
  May be taken as: Trigger logic about empty else clauses or null handling
  Say instead: "Only this matters to me"
- Says: "Elsewhere"
  Means: In another place or context
  May be taken as: Fragment into else + where, activating location-conditional logic
  Say instead: "Somewhere else or in another context"

## Tips
- Avoid 'or else' as a threat or ultimatum; models may flag or misparse it
- When listing options, say 'alternatively' instead of 'else' to avoid conditional syntax
- In prompts about decisions, separate your question from any 'what if not' framing
- Use 'otherwise' for natural language; reserve 'else' for explicit logical structure if needed
- If describing backup plans, say 'backup' or 'fallback' rather than 'the else case'

## Often confused with
- elif: chained middle condition, not final fallback
- otherwise: natural language equivalent without code syntax
- default: preset value, not conditional branch
- except: handles errors, not false conditions
- finally: always runs, not conditionally
- other: adjective describing alternatives, not control flow
