Etymology: Underspending is simply under- attached to spend, so its history is the history of its two parts. "Spend" came into English from Old English "spendan", which was borrowed from Latin "expendere", meaning to weigh out or pay out, and the Latin word traces back to a root that meant to weigh. Weighing out coins was once literally how payment was made, which is why the notion of paying out money sits so close to the idea of weighing. The prefix "under-" is much older and more basic. It descends from the Germanic word for "below" or "beneath" and was already present in Old English, where it carried both literal senses (beneath a surface) and figurative ones (inferior or insufficient). That is the sense that matters here: "underspend" means to spend below a set amount, and it is a transparent compound rather than an old word with a dramatic past.
