Perhaps you have heard the word “concur” used in the very short expression, “I concur,” meaning, I agree. The word literally means to run with. The “con-” prefix means with and is found in many words such as “concord” and “constant.” The “-cur” portion of the word is derived from the Latin for to run, as is found in words like “current” and “incursion.” Those who “concur” can be said to “run with each other” in the sense of “having ideas in the same direction.” The meaning is perhaps a bit stretched, but it will help you to remember it!

The word “expendable” literally means “able to be used” in the sense of “able to be used and then thrown away.” It does not necessarily mean that the item is cheap (though that might be the case).
