Swath is only a noun. It refers to (1) the width of a scythe stroke, (2) a path made by mowing, or (3) something likened to a path made by mowing. Today, it’s usually used in the third, figurative sense.
Swathe is usually a verb, meaning, primarily, to wrap or bind with or as if with bandage. It also functions as a noun meaning a wrapping or bandage, but it is rarely used this way in today’s English.
