The word dilemma has caused a dilemma.
According to Oxford Dictionary (http://www.oxforddictionaries.com/definition/english/dilemma) Pronunciation is : /dɪˈlɛmə, dʌɪ-/
Which is di-lema or dye-lema.
The website "howjsay" (http://www.howjsay.com/index.php?word=dilemma) also gives two pronunciations.
I just don't understand why it has two pronunciations. Also, is one UK and the other US? I am unclear as to which pronunciation I should stick to. Does it vary according to its position in the sentence? Or should I randomly shoot the one the pops up in mind?
Any assistance would be highly appreciated.
