what's the difference between speak and talk semantically?
- Hm... Well, one is more formal than the other. Furthermore you can speak French, but you can hardly talk French. Fyrius 16:55, 11 October 2009 (UTC)
Transitive usage? 
Should we include a transitive definition for "talk" in the verb section? I notice there is a (recent?) usage of "talk" in constructions like "we're talking Noah's Ark here" (example taken from an article by Richard Dawkins). "To talk", it seems, can now also have an object even without any prepositions involved. Fyrius 17:00, 11 October 2009 (UTC)
