Etymology
Origin of irreplaceable
First recorded in 1800–10; ir- 2 + replaceable
Explanation
The adjective irreplaceable describes anything that's one of a kind, particularly if it has deep sentimental value to you, like your grandmother's irreplaceable engagement ring. When you replace something, you get something that's just like it, but if something is irreplaceable, there's just no substitute. It might be a special thing given to you by a loved one, like your great-grandfather's pocket watch or something that can't be made again, like an irreplaceable painting or an old floor made from a species of wood that's no longer harvested.
