Ludwig's WRAP-UP

The phrase "I supposed to do" is grammatically incorrect and requires correction. As Ludwig AI highlights, the omission of the auxiliary verb (am, was, etc.) before "supposed" results in a non-standard English construction. To express obligation or expectation correctly, use "I am supposed to do" (present) or "I was supposed to do" (past). Alternative phrases include "I should do", "I need to do", or "I am meant to do", depending on the intended meaning. Therefore, it's crucial to include the appropriate auxiliary verb to ensure clarity and grammatical accuracy in both formal and informal contexts.
