Invaluable vs. valuable

Invaluable and valuable are nearly synonyms, despite the potentially misleading negative prefix in- on invaluable. Valuable means of considerable value, and invaluable means incapable of being valued. If you need an opposite of valuable, there are many options such as inexpensivecheap, and worthless

The difference between invaluable and valuable can be subtle, but think of it this way: valuable usually applies to things that have monetary value, while invaluable usually applies to things that can’t be valued in monetary terms. For example, a hoard of gold is valuable, while a good friend is invaluable (i.e., can’t be valued in monetary terms—hence the negative prefix in-).

Both words are about five centuries old, deriving from value around the early 16th century (value came to English shortly before from Anglo-Norman and Middle French roots). The Oxford English Dictionary records examples of invaluable used to mean having little value from the 17th and 19th century, but this sense has never been widely used. In historical Google Books searches covering the 18th and 19th century, every instance of invaluable that we find is in the sense incapable of being valued.
