Bit is a portmanteau of binary digit.
A byte is 8 bits.
A nibble is 4 bits (half a byte).
Is there a word for a pair of bytes?

It is word which is 16 bits.
They are (in order of increasing size)
BIT, NIBBLE, BYTE, WORD, DWORD, FWORD, QWORD, KiloByte, MegaByte
Please note that a word is the standard memory bus width in your architecture. It can be 8 bits or 16 bits or 32 bits or 64 bits based on the CPU.
You can read more about assembler(binary) here (this is a random link I found on google for your reference, but I verified that the information is correct about the above mentioned. Search on google).

3If word is so flexible, how can it definitively mean "a pair of bytes" if byte means only eight bits? – Robusto Mar 19 '13 at 12:14

@Robusto: A
wordis 16 bits in a conventional sense. As a matter of fact, the most common architecture even in the present day is x86-32, in which awordis 16 bits. Like @coleopterist mentioned in his comment, more details can be found at en.wikipedia.org/wiki/Units_of_information – Fr0zenFyr Mar 20 '13 at 10:42 -
1@Fr0zenFyr A word is 32 bits on x86-32 and 64 bits on x86-64. Some x86-specific technical documents use "word" to mean a 16-bit value for consistency with documentation and software written for 8086 processors, which had 16-bit words. This usage of "word" does not mean that x86 processors use 16-bit words. See the list of word sizes at en.wikipedia.org/wiki/Word_(computer_architecture) – Heatsink Mar 20 '13 at 15:36
I will offer this up as a suggestion, though I don't believe it was ever used in serious writing. A playte is unambiguously 16 bits, and also; chawmp in the context of a 32 bit machine.
I would've just commented on the previous answer but I don't have enough reputation yet, so I'll leave an alternate answer instead.
Also, I believe nybble is the correct spelling for four bits.
