Trivia Why is "I am as lazy as them" wrong in English grammar?

[plhbg1]

It is wrong because the subject of the sentence is “I” and when we use a comparative phrase such as “as … as” the pronouns on both sides of the comparison must be of the same part of speech and follow its rules. So the sentence should be “I am as lazy as they [are].” You would not say, for example, “I am as lazy as them [are].”
