Which of the following phrases indicates a non-native speaker's negation pattern?

The phrase "He no eat" illustrates a typical negation pattern that can emerge in the speech of non-native speakers of English, especially those influenced by their first languages. In many languages, negation may not follow the auxiliary verb structure commonly used in English.

For instance, in some languages, the word for "no" is used directly before the verb to negate it, resulting in constructions that don't incorporate the necessary auxiliary verbs to express negation in English. Consequently, "He no eat" lacks the correct auxiliary verb and grammatical structure typical of English, serving as an indicator of a non-native speaker's approach to negation.

In contrast, the other phrases employ correct English negation forms. "He can’t eat" uses the contraction of "cannot," "He doesn’t eat" employs "does not" in a standard way to convey present tense negation, and "He isn't eating" uses a standard contraction of "is not" for present continuous tense. These structures reflect an understanding of English grammar that is usually consistent with native usage, further emphasizing why "He no eat" stands out as indicative of a non-native speaker's pattern.
