Luckily the internet comes with a handy audio file teaching you how to pronounce this most tricky, yet useful, of words:
I find I can only pronounce 'amoureux' semi-properly if I lower my chin, cast my eyes sideways, and utter it in a low gravelly purr like a libidinous French baguette merchant (Boulanger?). Though whatever works for you! Ooh la la, c'est un baguette pour moi? C'est magnifique!
p.s. Yep grammar police, french for 'lover' (feminine) is indeed 'amoureuse', not 'amoureux'.
p.p.s. Haha 'Wiktionary', that's up there with 'Wookieepedia' (the Star Wars wiki).
