She is not my sister. ✅ I are at home. ❌ Are he sad? ❌ We no American. ❌ Is he your brother? ✅
In the phrase "We are American" versus "We are Americans," the distinction lies in the use of the adjective and the noun form of nationality. "American" is an adjective describing the quality or characteristic of being from America. Therefore, "We are American" describes a group of people possessing American characteristics. On the other hand, "We are Americans" uses the noun form, indicating that the individuals in the group are citizens or inhabitants of America. Both phrases convey similar meanings, but one emphasizes identity (as Americans) while the other emphasizes characteristics (being American).
