'non-standardly' originates from the prefix 'non-' meaning 'not' and the word 'standard,' which comes from Old French 'estandart,' meaning 'a rallying place or object.'

'non-standard' evolved from the combination of 'non-' and 'standard,' and the adverbial form 'non-standardly' was later derived to describe actions or behaviors.

Initially, 'non-standard' referred to anything not meeting a set standard, and 'non-standardly' evolved to describe actions performed in such a manner.
