# uns (5-uns.us)

Short for "unsaid" or "unspoken," or a casual way to say "us" in some dialects. People might use it to mean something left out, not stated, or implied without words.

## What a model may hear
- unsigned integer (C, C++, systems programming): treat the value as non-negative only, wrapping on overflow instead of undefined behavior
- unsupervised learning (machine learning): assume no labels are provided and look for hidden structure in data
- UNIX name service (legacy networking): expect a hostname or network naming query
- unsatisfiable (automated theorem proving, SAT solvers): report the formula has no valid assignment

## Where people and models part ways
- Says: "keep that uns"
  Means: leave something unspoken
  May be taken as: cast a number to unsigned, dropping negative values
  Say instead: "do not mention that part"
- Says: "the uns parts"
  Means: the parts we left out
  May be taken as: look for unsigned integer components in code
  Say instead: "the parts not stated"
- Says: "run it uns"
  Means: run it without saying how
  May be taken as: run unsupervised learning instead of a labeled approach
  Say instead: "run it without labeled data"
- Says: "check uns first"
  Means: check what was unsaid first
  May be taken as: check unsigned bounds before signed ones
  Say instead: "check the omitted details first"

## Tips
- Say "not stated" or "left out" if you mean something unspoken.
- Say "without labels" instead of "uns" for unsupervised learning.
- Say "non-negative only" if you want unsigned arithmetic behavior.
- Avoid "uns" alone when numbers or code are nearby.
- Spell out "unsupervised" in full in machine learning contexts.

## Often confused with
- und: German for "and," not English omission
- uni: one or universal, not omitted
- ums: uncertain or hesitant sound, not technical
- ins: in or insert, opposite of leaving out
- ons: Dutch for "us," dialect not standard English
