the word 'super-skinny' is a modern english compound formed by combining the latin-derived intensifying prefix 'super-' with the english adjective 'skinny'. the prefix 'super-', from latin super meaning 'above, over, beyond', is used extensively in english to denote an extreme or superior degree. the adjective 'skinny' itself evolved from the late middle english word 'skin', referring to the body's outer layer, and by the 16th century had acquired the sense of 'lean or thin', likely from the idea of having little flesh covering the bones. when combined, the morphemes create a term that logically extends the base meaning of 'thin' to an exaggerated, extreme state, reflecting contemporary usage in fashion and body description.

Structure: super (intensifier) + skinny (thin) super (latin origin, meaning 'above, beyond', functioning as an intensifying prefix); skinny (english origin, from the word 'skin', meaning 'thin, lean', functioning as the core adjective).
