'asnort' originates from English, specifically formed from the prefix 'a-' (a verbal/adverbial prefix) combined with the verb 'snort', where 'snort' is imitative of the abrupt nasal sound.

'snort' comes from Middle English 'snorten' (imitative), and 'a-' was added in later English usage to form verbs (giving 'a-' + 'snort' → 'asnort'); the combined form appears in 19th-century usage.

Initially it referred simply to making a snorting or nasal sound; over time it has also been used specifically to indicate expressing scorn or derision by snorting.
