I’d always presumed that the word ‘behoove’ meant, in effect, that one should ‘get a move on.’ I’d assumed that “hoove” had the same root as hoof, i.e. a horse’s foot. I found that amusing. But then I’m a sucker for foolish made-up games about word roots.
But it turns out that that ‘hoove’ like ‘have’ out of the root ‘kap’. Kap is also an ancestor of words like captive, accept, even deception. and recipe.
