kriging = Krige (opaque) = Krige + ing
The word is historically named after the surname Krige, but the meaning of a geostatistical method is not recoverable from the base name for most learners.
Etymology
Kriging is named after the South African engineer Danie Krige, who developed a way to estimate missing ground values from nearby samples. Think of Krige 'filling in' gaps from neighbours, which is why kriging means the method of making maps and predictions from limited data.
