• Prior to Christianization, god referred to a person's spirit within a tumulus.

• The word silly meant "blessed," but it eventually meant "innocent" (probably as regards women), and from there it connoted naive foolishness.

• The archaic word earg "cowardly" has gone blazed a bizarre semantic trail. In Proto-Indo-European it probably meant "sexually aroused," but in Late Proto-Indo-European it must have meant in one sense a virile sexuality but in another sense having sex with animals. By Proto-Germanic, however, it has come to mean "evil," perhaps thanks to the whole bestiality thing, but with a secondary metaphorical extension of a passive male homosexual (*not* in the active role, mind you). From passive gay we arrive at a sense of cowardice and the effeminate.

Dog, in that the etymology is largely unknown. Germanic supplied the modern "hound", while "canine" comes from Latin. The early forms of "dog" seem to have randomly appeared in Old English.

'Rook' in chess - from Persian 'rukh', or 'chariot'.

Nasty. From a Dutch word for nest as in a bird's nest. After birds shitting in a nest all spring and then rotting all summer, they could quite disgusting, and thus nasty to describe something befouled and gross.

The word "cumin" comes ultimately from old Sumerian, they called it gamun.
