In English you have the word "plaything" which can in certain circumstances have a sexually exploitive connotation when used in reference to a person. Would one use Spielzeug for that too or is there another word to translate the english plaything?
"Am I a toy?" Implies that I do not know if I am a toy or not. I saw the sentence as "I am a toy?" which implies I jut found out I am indeed a toy and cannot believe it. I was wrong but now I'm wondering how I convey "I am a toy?"
When the verb is used first, it is a question. The statement "I am a toy" = "Ich bin ein Spielzeug".... Unless maybe in Umgangssprache it is inflected.
