"Bring and take are two common, simple words that have gotten more than their share of attention by people unsure if they're using them correctly. The words are distinct in meaning, but—and this is a big but—much of the time the context makes it irrelevant which you use, and that's why there's a problem.
Insofar as bring and take are distinguished, bring is used for movement towards the speaker or the speaker's point of reference, and take is used for movement away from or accompanying the speaker or the speaker's point of reference. Thus, two sentences that shouldn't cause much trouble are: 'Please bring me a cup of coffee' and 'Take that smelly dog away from me!' Neither of these examples could have the other word substituted."
"Chaser isn’t just a 9-year-old border collie with her breed’s boundless energy, intense focus and love of herding virtually anything. She’s a grammar hound. In experiments directed by her owner, psychologist John Pilley of Wofford College in Spartanburg, S.C., Chaser demonstrated her grasp of the basic elements of grammar by responding correctly to commands such as 'to ball take Frisbee' and its reverse, 'to Frisbee take ball.' The dog had previous, extensive training to recognize classes of words including nouns, verbs and prepositions."
