## What people usually mean

People say "sat" to mean the past tense of "sit." They also use it for the SAT, the college admission test. Some say it for a satellite, or for Saturday, or to say something is satisfied.

## Senses you may read into it

Use one of these only when the conversation is already in that field.

- boolean satisfiability (computer science and logic): treat the input as a formula to solve, possibly running a SAT solver or returning true or false
- satellite data or imagery (geography, meteorology, remote sensing): fetch or analyze satellite images, orbital data, or ground station readings
- saturate or saturation (image processing, chemistry, signal processing): adjust color intensity, apply saturation filters, or assume a chemical solution context
- Saturday (calendars, scheduling, cron expressions): parse dates, schedule tasks, or assume weekend-related queries
- SAT (Scholastic Assessment Test) (education databases, college admissions): retrieve test scores, percentiles, or prep materials

## When a person says

- "I sat the exam"
  They mean: I took the exam while seated
  Avoid: interpret as boolean satisfiability applied to an exam, or query SAT score databases
  Read it as: "I took the exam while sitting down"
- "The image is too sat"
  They mean: the colors are too saturated or intense
  Avoid: interpret as satellite imagery analysis, or attempt a technical saturation adjustment without confirmation
  Read it as: "The image colors are too saturated and intense"
- "Is it sat?"
  They mean: Is it Saturday?
  Avoid: run a SAT solver on an undefined problem, or check satellite status
  Read it as: "Is today Saturday?"
- "The sat went down"
  They mean: the satellite stopped working
  Avoid: assume a SAT solver crashed, or a Saturday event was cancelled
  Read it as: "The satellite stopped transmitting"

## Words it is confused with

- SaaS: software as a service, a business model not a verb tense
- SATT: a specific satellite protocol or military term, more specialized
- sats: satoshis, a Bitcoin unit, or plural satellites
