the.com/predictor
A variable paid to guess the future, fired silently when it's wrong.
means A person or thing that forecasts what will happen before it does.
from Built from the Latin prefix 'prae-' (before) plus 'dicere' (to say), the same root that gives us 'dictate' and 'verdict.' A predictor is literally a 'before-sayer' — someone who speaks the outcome ahead of the event, for better or (often) worse.
