IPA: /ˈɡɛsˌwɜrk/
KK: /ˈɡɛsˌwɜrk/
A process of making estimates or judgments based on incomplete information or intuition rather than facts.
The scientist's conclusions were based on guesswork rather than solid evidence.
Guesswork → It is formed from "guess" (originating from Middle English *gessen*, meaning to estimate or suppose) and "work" (from Old English *weorc*, meaning effort or activity). The term "guesswork" refers to the process of making an estimate or assumption based on incomplete information or intuition.
Think of making an 'estimate' ('guess') and putting in 'effort' ('work') to figure something out — that's what guesswork means.
