I have always taken this at face value. I mean, our teachers should know, right? So I checked my favourite online dictionary, the Oxford Dictionary, and here is now Oxford defines it:
Now, in the second definition, it's only in the context of philosophy that dilemma indicates only 2 alternatives, but in general everyday use, a dilemma can refer to 2 or more alternatives. Now I dislike being wrong, but I'm glad that something made me want to look up this word so that I could learn its definition.
Of course, being that the way I learned about dilemma was slightly faulty, I had to question my knowledge of the definition of predicament. Here's how Oxford defines it:
So it seems that my understanding of the word predicament was definitely off as well, but at least I don't feel that I've been using it incorrectly all my life! I haven't been using dilemma incorrectly, either, only that there were more instances where I could have used it than I did.
No matter how much you know about a subject, there is always going to be something new to learn! I still think that the person in the show used the term incorrectly, however. I fail to see what her unpleasant alternatives were. She had a choice between dressing well for the party or not dressing well. Perhaps her implication was that she didn't know how to choose the right outfit for the party, so if left to her own devices, she would have had a dilemma because all her choices would have been wrong, and that's why she needed the assistance of experts. Maybe I just think too deeply about it!
