Blend, also blending， is the term for portmanteau word In morphology, a relatively unproductive process of word formation by which new words are formed from the beginning (usually the first phoneme or syllable) of one word and the ending (often the rhyme) of another, or by joining the initial parts of the two words. Examples of blends formed this way are English smog (fermed from smoke and fog), brunch (breakfast and lunch). Blending is usually not considered part of I-Language.
