What does descendent mean?
A descendent is a person, animal, or plant that has descended from a particular ancestor — in other words, an offspring of later generations within a family line. When we say someone is 'a descendent of Irish immigrants' or 'a direct descendent of a historical figure', we are tracing a line of inheritance, whether of blood, property, titles, or even ideas and traditions. The word carries a sense of continuity across generations, linking the present to the past, and it appears frequently in genealogy, history, law, and biology. In everyday writing, however, you are far more likely to encounter the spelling 'descendant', which means precisely the same thing and is now the dominant form in both British and American English; 'descendent' survives chiefly as a recognised but uncommon variant. The word derives from the Latin verb descendere, meaning 'to climb down'. Its opposite is an ancestor or forebear — the one at the top of the family tree from whom all descendents flow downward through time.

Both 'descendent' and 'descendant' come from the Latin for 'to climb down' — so every descendent is, literally, someone who has climbed down your family tree.

Etymology of descendent
Descendent comes from the Latin verb descendere, formed from de- ('down') plus scandere ('to climb'), literally meaning 'to climb down'. The word entered English via Old French descendre in the late Middle English period, originally as an adjective meaning 'descending' before settling into its primary noun sense of one who issues from an ancestor. It shares this root with related words such as 'descend', 'descent', and the more common variant spelling 'descendant', which has largely displaced it in modern usage.
