Words that begin with "ch"

I took a short hike today, and inexplicably became obsessed with the number of French words that I know which start with "ch". These are the ones I could come up with off the top of my head:

• chacun - each
  
• chaise - seat/chair
  
• chalet - chalet
  
• champagne - champagne
  
• champignon - mushroom
  
• chance - luck
  
• chanteuse - singer (f)
  
• chapitre - chapter
  
• chaque - each
  
• charme - charm
  
• chauffeur - driver
  
• chaussure - shoe
  
• chemin - road (e.g. chemin de fer - railroad)
  
• cheval - horse
  
• chèvre - goat
  
• chien - dog
  
• chiffre - cipher (as in code) or number
  
• choc - shock
  
• chocolat - chocolate/hot chocolate
  
• chômeur - unemployed
  
• chose - thing (or something)

In running through my French dictionary, I noticed a few that I didn't think of - chambre (room); change (exchange); chanson (song); chapeau (hat); chapelle (chapel); chat (cat); etc etc. There are about 400 words beginning with "ch" in my dictionary, and I know perhaps 5% of them. Room for improvement. I wonder if this carries over to the entire dictionary. It seems unlikely that I know 5% of all those words.
