Origin & History of “size”

The etymological notion underlying size is of ‘settling’ something, of fixing an amount. The word is a curtailed version of assize, which went back ultimately to Latin assidēre, literally ‘sit beside someone’. By the time it reached English, via Old French, it had acquired connotations of ‘sitting down to make a judgment on something’, such as a law case (hence the meaning of English assize). other matters decided on in this way included the standardization of amounts (of taxes, e.g., or food), and this led to the word size being used for ‘dimension’. Size ‘gum’ (15th c.) may be the same word, but the nature of the relationship between the two is unclear.
