ancestor: [13] Ultimately, ancestor is the same word as antecedent [14]: both come from the Latin compound verb antecēdere ‘precede’, formed from the prefix ante- ‘before’ and the verb cēdere ‘go’ (source of English cede and a host of related words, such as proceed and access). Derived from this was the agent noun antecessor ‘one who precedes’, which was borrowed into Old French at two distinct times: first as ancessour, and later as ancestre, which subsequently developed to ancêtre. Middle English had examples of all three of these forms. The modern spelling, ancestor, developed in the 16th century.
