Multiverb construction

How does “see” come to mean “try”?

Verbs of seeing repeatedly become markers of attempting. Japanese 食べてみる “eat and see”, Korean 먹어 보다, Mandarin 試試看, and the Turkic converb + kör- constructions all say “do it and see” for “try doing it”; Voinov (2013) traces the co-lexification across Eurasia, New Guinea, India, and West Africa.
