Sort by Every Other Row?

[KeithS]

Hi - I have several long lists (each is 600+) of vocabulary words & definitions and need to alphabetize/sort the words, but need to keep the definitions w/ the words.

A1 = word 1
A2 = def. 1
A3 = word 2
A4 = def. 2
A5 = word 3
A6 = def. 3

Standard sort will alphabetize all rows & the words will be separated from the definitions. I could group rows 1 & 2 together, rows 3 & 4 together, etc. but that's clunky & time-consuming. Any advice? I'm using Excel 2010.

Thanks!
