Sense: noun/1

A guesser forms answers based on limited information, often with luck involved. An estimator calculates rough values using some data or method, making it more systematic and common in technical fields. A speculator guesses about future events—especially financial ones—with risk and reward in mind. A forecaster uses data and models to predict future trends like weather or sales. A predictor is similar but broader: it can refer to anyone or anything (including machines) that says what will happen. While a guesser may be right by chance, forecasters and predictors are expected to have evidence behind their statements.

Etymology

Old NorseMiddle EnglishEnglish

Formed from the verb guess (which came into Middle English from Old Norse geta, meaning 'to get' or 'to guess') combined with the agent suffix -er, which marks a person who performs an action. The word has been used since at least the 16th century to describe someone who forms opinions without certain knowledge.
