'anarthrously' originates from English, specifically from the word 'anarthrous' with the suffix '-ly', where 'an-' meant 'without' and 'arthrous' referred to 'having an article'.

'anarthrous' comes from Greek 'anarthros', meaning 'without joints' or 'not articulated', and in linguistics, it came to mean 'without an article'. The adverb 'anarthrously' was formed by adding '-ly' to the adjective.

Initially, it meant 'in a manner without joints or articulation', but in modern linguistics, it evolved to mean 'in a manner lacking an article'.
