Learn French: Goal One - words that end in -eau are masculine

This one was almost too easy; I could think of numerous examples. Unfortunately some of the examples proved to be exceptions to the rule!

• l'eau - water - oops, this is an exception, it is a feminine word, crap!
  
• la peau - skin - another exception, nf!
  
• le rouleau - roller
  
• le couteau - knife (easy to remember because it sounds similar to "cut")
  
• l'oiseau - bird
  
• le gâteau - cake
  
• le bateau - boat
  
• le chapeau - hat
