relate: [16] Something that is related to something else is etymologically ‘carried back’ to it. The word is based on relātus, the past participle of Latin referre ‘carry back, refer to’ (source of English refer). (Lātus was not the original past participle of Latin ferre ‘carry’; it was drafted in from tollere ‘raise’, source of English extol and tolerate.) Derivatives in English include relation [14] and relative [14].
