How can you find a transitive verb of incomplete predication?

You can find a transitive verb of incomplete predication, when you do not have the Direct Object. I mean, when the DO is hidden.

For ex: "He wrote me". You can ask: What did he write? And you can answer: a letter, an email, etc...

He: Subject

wrote me: Predicate

wrote: Main Verb / Transitive Verb of Incomplete Predication

me: Indirect Object

In this sentence you do not have the DO (a letter, an email, etc)... so the pattern verb is TVIP.
