Other forms: proximately
Proximate things are either nearby or close in time. The proximate arrival of a new grandchild means your grandma had better finish knitting those booties. A Rube Goldberg machine is like a giant chain of proximate causes – one action causes another.
Use the adjective proximate for things that are close to each other or somehow related. Like the noun proximity, or nearby area, it comes from the Latin root, proximus, "nearest." In legal terms, you may have a case if the proximate cause of a fall was someone’s negligence. You can use proximate to mean "imminent" (or close by, but in terms of time), as in "The proximate publication of her story made her both nervous and excited."
