The adverb 'systematically' is built upon the noun 'system', which originates from the Greek sustēma, meaning a whole composed of several parts or members. This Greek term itself derives from the verb sunistanai ('to combine, to set up together'), formed from syn- ('together') and histanai ('to cause to stand'). The suffix -atic was borrowed from Latin -aticus, a common adjectival ending, to create 'systematic', meaning 'relating to or constituting a system'. Finally, the English adverbial suffix -ally (from Latin -alis + -ly) was appended, transforming the adjective into an adverb that describes an action performed in a methodical, organized, and step-by-step manner, reflecting the inherent order of a 'system'.
