For example, the English word spoor comes right from the Afrikaans spoor, meaning trail or track. This is from an identical Dutch word which is descended from the Proto-Germanic *spurą, from which came an Old English word- spor. (Also spurn)
Another example of this is with valkyrie, the English word for the choosers of the slain in Norse mythology. Etymonline says it entered English in the 1700s, from the Old Norse. (From valr + kjósa, the Proto-Germanic roots of which are from where choose and the Middle English wal come from.) However, Old English had a word for the Valkyries too- wælcyrge.
So my question is, can we call valkyrie and spoor (plus similar borrowings, like falcon when we had the Old English fealca) cognates of the Old English words, or are they just borrowings?
