think on (someone or something)

think on (someone or something)

To contemplate, ruminate over, or reflect on something. I've been thinking on this issue all week, and I've come up with a few possible solutions. A: "I'm not willing to uproot my whole family just for some job." B: "Look, just think on it for a couple days, all right?" I found myself thinking on my best friend from elementary school the other day. I wonder what ever happened to him?
