Can All Americans Speak English with Perfect Grammar?

No, not all Americans speak English with perfect grammar. The English language, while the primary language in the United States, encompasses a wide range of dialects, accents, and proficiency levels. Various factors, including education, regional variations, cultural influences, and individual language backgrounds, contribute to the variations in grammar usage and fluency. Additionally, many Americans use informal speech patterns or slang that deviates from standard grammatical rules.

Grammatical Differences in American English

While there are grammatical differences between American English and British English, both are spoken grammatically correctly by most people. In my six years living in the USA, I had no difficulty with American English.

It is unlikely that all Americans adhere to grammatical rules every single moment. We sometimes split infinitives, end sentences with prepositions, or have subject-verb disagreements. Occasionally we use nonstandard English as an intensifier or for humor. Some of us speak a regional English that sounds less than correct to people from other parts of the country. However, if the question is whether people in the USA generally sound literate, most do.

Native-Born American English Speakers

I answer under the assumption that you mean native-born Americans, as those who learn English as a foreign language face additional challenges in speaking correctly. There is tremendous variation in the level of grammatical correctness spoken in our country, depending on one’s level of education, upbringing, and socioeconomic factors. Despite this, we can generally communicate with each other, and poor grammar does not typically equate to a lack of intelligibility or comprehension.

Grammar vs. Communication

I would say 'no.' Most Americans, including highly educated individuals, do not sound like textbooks. When considering language, there is a difference between 'letter' and 'spirit.' The 'letter' of the law is what the rules say, while the 'spirit' is the overarching intent. In language, the 'letter' (grammar) is important, but you can't let the rules get in the way of the point.

A common example is dropping the -ly ending, such as 'That was real good!' rather than the grammatically correct 'That was really good!' While this is not technically correct, it is extremely common in spoken English. Another example is the use of 'ain't,' which is not an actual word. In American English, people often have different 'sets' of English tailored to their audience, and sometimes this involves speaking in a grammatically incorrect fashion. However, as long as it serves the spirit of communication, it is acceptable.

I, for instance, speak English differently in various settings. When teaching in a professional setting, I use a different vocabulary and accent compared to when hanging out with relatives in Kentucky or with my British colleagues. This speaks to the idea that most people modify their language to 'play to their audience,' sometimes at the expense of grammatical correctness. However, as long as the communication remains clear, the grammatical flaw is often overlooked.
