hipótesis
/iˈpotesis/ · B2 · noun · f
hypothesis
🔬 hipó-tesis = hypo (under) + thesis (placement): an idea placed underneath, to be tested
Greek hypo means under and thesis means a placing. A hipótesis is the base proposition you place under an investigation, the starting point you then test. Spanish keeps the h silent, so say i-PO-te-sis.
