'awesomeness' originates from English, specifically the word 'awesome' plus the suffix '-ness', where 'awesome' was formed from 'awe' + the suffix '-some' (meaning 'characterized by').

'awesomeness' was formed by combining the adjective 'awesome' (late 16th century, meaning 'inspiring awe') with the noun-forming suffix '-ness' (Old English origin). The root 'awe' goes back to Old English 'ege' (or 'ege' variants) meaning 'fear/terror' and is related to Proto-Germanic roots for fear.

Initially, the root 'awe' primarily meant 'terror' or 'fear'; over time it shifted toward 'profound respect or wonder.' Consequently, 'awesomeness' now denotes the quality of inspiring deep admiration or, colloquially, extraordinary excellence.
