Only an in- separates the words valuable and invaluable. As it turns out, that small in- is worth a lot when it comes to the different meanings of valuable and invaluable.

In this article, we will prove our worth by breaking down the difference between valuable and invaluable, explain how they are typically used, and give examples of how they can be used in sentences.听

invaluable vs. valuable

The word valuable is an adjective that means 鈥渉aving a large monetary worth,鈥� 鈥渉aving admirable qualities,鈥� or 鈥渦seful.鈥澛�

For example:

• That painting is very valuable, costing millions of dollars.
• Stephanie has been a valuable friend to me for many years.
• Patience, charisma, and cleverness are valuable skills for a politician to have.听

The word invaluable is an adjective that means “beyond calculable worth” or “priceless.” It is used in this sense both literally and figuratively.听

For example:

• These ancient scrolls are invaluable because no amount of money could replace them.听
• Dr. Reed鈥檚 contributions to the field of medical science have been invaluable.听

The word invaluable is interesting because it appears as though it should mean the opposite of the word valuable, but it doesn鈥檛. However, invaluable is not a synonym of valuable either. Instead, invaluable is a stronger word than valuable and is used to describe something as having a value that is so large that it is impossible to calculate.听

The words invaluable and valuable cause confusion in much the same way as the word pair inflammable and flammable, which are actually synonyms. Unlike inflammable, though, the word invaluable actually does use the prefix in- to mean 鈥渘ot.鈥� How is that possible if valuable and invaluable aren鈥檛 opposites?

You see, the word invaluable technically means 鈥渘ot valuable,鈥� but not in the way we usually think. Both invaluable and valuable come from the verb form of value in the sense of 鈥渢o calculate the monetary worth of,鈥� as in They valued this painting at $3 million. The word valuable combines value and -able together. If something is valuable, you are able to value it as being precious or worth a lot of money. By contrast, invaluable combines in- (鈥渘ot鈥�) with valuable. If something is invaluable, it is not able to be valued because its worth is so high that it is impossible to assign it an actual number.
