'asymmetrically-separated' originates from the combination of 'asymmetrical' and 'separated'. 'Asymmetrical' comes from Greek 'asymmetros', where 'a-' meant 'not' and 'symmetros' meant 'measured together'. 'Separated' comes from Latin 'separatus', the past participle of 'separare', where 'se-' meant 'apart' and 'parare' meant 'prepare'.

'Asymmetrically-separated' evolved from the combination of 'asymmetrical' and 'separated', which were used in English to describe objects or concepts that are not evenly divided.

Initially, 'asymmetrical' meant 'not measured together', and 'separated' meant 'set apart'. Together, they describe something divided in a non-uniform manner.
