Definitions:

(1) (vagrant)
someone who is poor and has no regular home or job
(2) (meaning too rare to warrant focus)
Less commonly, and especially long ago, you may see vagrant used to emphasize that a poor person wanders from place to place. Even more rarely, it can describe an animal as being in a place it usually is not, or to describe anything that varies or seems random such as the seeming haphazard direction in which a certain weed spreads, or the fleeting quality of something smelled for only an instant.
