Portmanteau words, also called blends, are words formed by merging or blending two or more existing words.

The words “breakfast” and “lunch” blended form the portmanteau word “brunch.’’
A brunch is a meal combining both breakfast and lunch. It is usually eaten in the late morning.
Although portmanteaus can be used in most situations, they are generally used in informal situations and creative writing.
Most portmanteaus are formed with the first segment of one word and the last of another.
