The author researches selected synonyms of 'skinny' and 'fatty' in the history of the English language from the perspective of cognitive linguistics. The method employed in grouping the analytical material has been dictated by the nature of the processes of semantic change. The author subdivided the quantum of the analysed lexical items into the following type-groups: zoosemy (animal metaphor), foodsemy (food metaphor), plantosemy (plant metaphor), metonymy, reification, eponymy, onomatopoeia, rhyming slang and varia. Surveying a collection of English dictionaries the author makes an attempt to determine the status of a given synonym in present-day English.
