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

First thing I thought of were the months janvier and février. Do those count? I guess so. Mostly I came up with things similar to English words...

• janvier - January
  
• février - February
  
• l'escalier - stairs (this word is plural masc.)
  
• le panier - basket (similar to the English word pannier)
  
• le courrier - mail, letters (plural masc.) (similar to the English courier)
  
• le croupier - croupier, identical to the English.
