The 14 in "pic14" does not refer to anything in the part number or series 
name, but instead to the size of the instruction word. These 
microcontrollers use completely separate instruction and data busses. The 
data bus is 8 bits wide, like most small microcontrollers, but the 
instruction bus is 14 bits wide. This is indeed quite strange.

Likewise, the 16 in "pic16" also refers to the size of the instruction 
word and nothing in the part number or series name.
