In this article I address a hitherto used buzz phrase in English, "Yes, we can." This phrase represents various forms of meanings--challenge, possibility, ability, permission and opportunity in social, political and linguistics domains. I consider the syntactic and the semantic properties of "Yes, we can." I also compare its conventional usages with more recent treatments. The catch phrase "Yes, we can" has standard usage in sports, music, language, literature and politics. Candidate Obama elevated it as a slogan in his presidential campaign. (Contains 3 tables.)
