• My shoes are [of] the wrong color.
  • This new wallpaper is [of] an odd pattern.

At first, one could say these are noun phrases functioning as predicate nominatives; however, the awkwardness in meaning suggests that a preposition was omitted and the subject complement is actually an adjectival prepositional phrase. Is this the case? If so, when is the omission allowed?

  • The only hidden preposition I see is "on".

    what do you mean by "the awkwardness in meaning"? how are these examples awkward similarly awkward?

  • Could you clarify your meaning? None of these sentences read as awkward to me, and none of them require a preposition. In fact, inserting of makes each sentence more awkward! Mar 17, 2021 at 1:27

    "My shoes are the wrong color" appears the same construction as "My shoes are green". No awkwardness or missing pronoun there.

“Of” is not simply redundant, it changes the meaning slightly. “Of” indicates that the object belongs to a certain category, undesirable in the given context.

Not merely a random wrong (or odd) item — an item of the wrong kind.
