"I am waiting for my husband."
Translation:Čekám na muže.
unfortunately if we always use manžel and manželka (or any other word in other sentences), users might never learn that there are alternatives. Duolingo does not allow for multiple translations to be "visible" to users. "Můj muž" and "moje žena" is also more common in spoken language and so it is important that users know those words.
