>English cognate to "atreve" is "attribute".

I didn't know that, but you'll grant me that it's not a very useful cognate (either in spelling or in meaning).

>~ов is an iterative suffix - like ~le or ~er in gamble and chatter. It's useful to know, because you can rationalise why it is always dropped in the present tense - you can't be iterative at the moment, unless you're an Englishman)

Very interesting, thanks.
