Up until very recently, ch and ll were proper spanish letters, so when looking up on the dictionary, you would find chancla in a separate chapter, after cordón (ch would come after c in the alphabet). Same with llama and loro (ll being after l). They nowadays maintain their own phoneme but have been demoted to irregular pronunciation, from letter without proper symbol.
