Blending (or fusion, or portmanteau) is a specific type of shortenings, which implies “packing” of two meanings into one word. The process is also called telescoping because the words slide into one another like sections of a telescope.
Sound- interchange is a non-productive type of word formation when two words usually connected semantically and etymologically have different sounds (vowels or consonants or both) in their phonetic structure, like speak-speech, blood-bleed, food-feed, etc.
Stress- interchange is one of the ways of word-building, based on a shift of stress, e.g. ‘object – to ob’ject; ‘present – to pre’sent, etc.
Lexicalisation is the process of the vocabulary replenishment when the plural form of nouns (grammatical inflection) loses its grammatical meaning and becomes isolated from the paradigm, as e.g. arm+s = arms= ‘weapons’, custom+s= customs=‘institution controllong import duties’.
Adjectivisation is the process of the vocabulary replenishment by means of the process of transition of nouns and participles into adjectives.
