digest: [15] English took the verb digest from dīgest-, the past participle of Latin dīgerere. This was a compound verb formed from the prefix dī- ‘apart’ and gerere ‘carry’, and originally meant ‘divide, distribute’ – a sense which developed via ‘dissolve’ into the specifically physiological ‘dissolve and obtain nutrients from food in the body’.

A further semantic offshoot of ‘distribute’ was ‘orderly arrangement’, and in fact the earliest use of the word in English was as the noun digest ‘summary of information’ [14], from Latin dīgesta, the neuter plural of the past participle, literally ‘things arranged’.
