I'm dutch and my english is just on conversation level acceptable. Now I have to write a letter and I'm having serious doubts about using "a" or "an" here. As the word "unique" opens with a vowel, it should have "an" with it, but as in the pronounciation sounds a "y" first, it sounds weird to say "an unique... whatever", so it doesn't feel right to write it either. Is this an exeption and is there a difference between writing and pronouncing, or am I completely wrong and is only "an unique" really correct? Thank you very much for your help!
