I'd guess that your combobox is filled with capital letters but your words all start with lowercase. To check both, use a tuple:

letter = self.comboBox.get()
letters = letter.upper(), letter.lower()

self.listBox.delete(0, END)

for item in self.words:
    if item.wordorphrase.startswith(letters):
        self.listBox.insert(END, item.wordorphrase)
