Usage

What does -bound mean? The combining form -bound is used like a suffix that has two distinct senses.The first of these senses is “tied, in bonds” or "detained," and this form of -bound is occasionally used in a variety of everyday terms, especially in reference to inclement weather. The form -bound in this sense comes from the past participle and past tense of the verb bind, meaning “to fasten or secure with a band or bond.”The second of these senses is “going or intending to go; destined,” and this form of -bound is occasionally used in a variety of everyday terms, especially when indicating a direction or destination of travel. The form -bound in this sense ultimately comes from Old Norse būa, meaning “to get ready.”Not every word that ends with the exact letters -bound, e.g., abound or rebound, is necessarily using the combining form -bound to denote “tied” or "destined." Learn why abound means “to occur in great quantities” at our entry for the word.
