Expert writing Tips
Best practice
Always include the necessary auxiliary verb (am, is, are, was, were) before "supposed to" to ensure grammatical correctness. For example, use "I am supposed to use" instead of "I supposed to use".
Common error
Avoid omitting auxiliary verbs like "am", "is", or "was" before "supposed to". This omission leads to ungrammatical sentences that can confuse your readers. Always double-check your sentence structure to include these necessary verbs.

Ludwig's WRAP-UP

The core issue is the omission of the auxiliary verb (am, is, was, were) before "supposed", which is essential for conveying obligation or expectation in standard English. Common correct alternatives include "I am supposed to use" (present obligation) and "I was supposed to use" (past obligation). This error should be avoided in all forms of writing, particularly in formal or professional contexts. Correcting it with an auxiliary verb makes it grammatically sound.
