The combination of kanji doesn't make perfect sense, but it's alright. Take something that's middle old and you have something that's used or secondhand. It's not 100% old yet... it's still in the middle, meaning you can give it to someone else to use, like your younger siblings.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
