The word "random"

The word "random" is a fake friend (false friend): the "dom" ending is to the -dom fastening. Indeed, it is of Frankish fromth (randon<randir), albeit in of Theedish fromth as the rand in random is kindred to the English  to run or less likely the.

The run link is because the meaning of the word at first meant rashfully fast and only after 1500 it meant —after all, fast happenings are often unbridled. As the shift of meaning is English, it could be that if the Norman  never had happened a word linked with running would have become to mean "random", say the made up word ranhood.

A small aside, "chance" is of Frankish fromth, while the OE word wyrdgesceapum can be to weirdshape —weird (OE wyrd) once meant "fate".
