This study was designed to examine the differences between two world Englishes in an effort to add to the body of knowledge relative to world Englishes and cross-cultural communication. Specifically, select grammatical differences between a group of Filipino English language teachers and a Standard American English were examined. Differences between the grammars of the two English varieties included article use, collocations, pluralization of mass nouns, question formation, and verb tense. Proceeding from the premise that cross-cultural communication can be problematic due to the differences between world Englishes, in this case, grammar, this study showed differences in grammar between the two Englishes that could result in miscommunication.
