* "round out " means to bring to completion a synonym would be "fill out" "finish off" or "finish" so the sentence means that a good sense of intuition made her arsenal complete Example:"These studies round out the results of many years of research" * "out think" means "out wit" which means "gain an advantage through cleverness" it's the same as "outsmart" I hope this clears things up for you.

Hmm it should say rounded off, not out. :( Rounded out, means to cut a spherical shape in to something, rounded OFF means to finish. At least in English it does. Out-think is just what Mizo said. To be more intelligent than someone else and to beat them because of it.

Thank you fdmaxey .

Mizo_Elgabry's definition of "round out" is correct. It might not be used in England, but in the U.S. it means to complete something. Examples: "We now have a complete team, with John rounding out the roster." "This new model car rounds out my collection of 1930's Ford cars."

Thank you Craig for all your corrections.
