Rŏs'ter, n.

n. [A corruption of register.]

1. (Mil.) A list of officers for duty. Scott.
2. Hence, sometimes, a list of the officers of a division, brigade, regiment, or battalion, containing, under several heads, their names, rank, the corps to which they belong, date of commission, and place of abode.

☞ This word is also used frequently instead of register, which comprehends a general list of all the officers of the State, from the commander-in-chief to the lowest in commission, under the same appropriate heads, with an additional column for noting the alterations which take place. W. H. Sumner.
