'anticipatingly' originates from Latin, specifically the word 'anticipare' (past participle 'anticipatus'), where 'ante-' meant 'before' and 'capere' meant 'to take'.

'anticipare' passed into Medieval Latin and then into Middle English as the verb 'anticipaten'/'anticipate'; the adjective/participle 'anticipating' developed from the verb and the adverbial suffix '-ly' was added to form 'anticipatingly'.

Initially it meant 'to take or act before (something),' but over time it evolved into the modern sense of 'to expect or foresee beforehand,' and 'anticipatingly' denotes acting or feeling in an anticipatory manner.
