# mod (10-mod.com)

People say mod when they mean a change or add-on to something. A gamer installs a mod to get new skins or maps. A hobbyist does a mod to their car or keyboard. It is short for modification, usually made by a fan or user, not the original maker.

## What a model may hear
- modulo operator (programming and math): compute the remainder after division, often used for wrapping indices or checking parity
- modular arithmetic (cryptography and number theory): treat numbers as wrapping around a fixed modulus, used in hashing and encryption
- module system (software engineering): import or isolate code units, as in Python modules, Rust modules, or Node.js CommonJS require
- moderator role (forums and platforms): filter content, ban users, or enforce rules automatically or by human action
- mod file format (music tracking and audio): play tracker music using sampled instruments in formats like .mod, .xm, .it

## Where people and models part ways
- Says: "add a mod to my game"
  Means: install a fan-made content pack
  May be taken as: treat mod as a mathematical operator and produce a remainder calculation
  Say instead: "install a fan-made content pack or modification for my game"
- Says: "use mod to fix the loop"
  Means: apply a user-made patch to correct behavior
  May be taken as: insert a modulo operation that breaks the loop logic with unexpected wrapping
  Say instead: "apply a user-made patch or modification to correct the loop behavior"
- Says: "mod the result"
  Means: alter or adjust the final output manually
  May be taken as: compute result % some_number as a modulo operation
  Say instead: "manually adjust or modify the final result"
- Says: "load the mod first"
  Means: initialize the add-on before the main program
  May be taken as: import a code module or compute a modulus before other steps
  Say instead: "initialize the add-on or modification before the main program"

## Tips
- Say modification or add-on when you mean user-made content, not the math operator
- Say module when you mean a code file or package to import
- Say modulo or remainder when you mean the math operation
- Specify the game, software, or platform name to steer the model toward the right domain
- Say fan-made or user-created to distinguish from official patches or built-in modules

## Often confused with
- modulo: strictly the math remainder operation, not user content
- module: a code unit or self-contained component, not a fan add-on
- mode: a setting or state of operation, not a modification
- modem: network hardware, unrelated to changes or additions
- modality: a method or mode of interaction, not a modification
