How to say "ancestor" in Japanese

Choosing the right word
  • 先祖せんぞJLPT N2approx.Common
    nounAncestors of one's own family, viewed across the generations; the natural choice for talking about one's forebears, family roots, or the ancestors one honours.
    ある出来事できごとを記念きねんしたり先祖せんぞの伝説でんせつを伝つたえるために建たてられたものであった。↗
    They were erected to commemorate a certain event or to tell an ancestral legend.
  • 祖先そせんJLPT N2approx.Common
    nounOne's ancestors, largely interchangeable with 先祖; it also serves for ancestry beyond one's own line, as of a people or of humankind.
    私わたしたちは祖先そせんをうやまうべきだ。↗
    We should worship our ancestors.
  • 祖そCommon
    nounMeans 'ancestor' or 'progenitor', but in practice it functions as a combining element inside compounds rather than standing alone; to say 'ancestor' in a sentence, use 先祖 or 祖先.
  • 先人せんじんCommon
    nounPeople who went before — predecessors, pioneers, forebears — with a respectful nuance. For one's literal family ancestors 先祖 or 祖先 is the word; 先人 stresses what earlier people achieved or left behind.
    彼かれは先人せんじんと同おなじ道みちを歩あゆむことを名誉めいよだと信しんじている。↗
    He believes it to be an honor to follow in his predecessor's footsteps.
  • 前身ぜんしんCommon
    nounMeans what something previously was — its antecedents or earlier incarnation — or a previous position or existence; it is not how you refer to family ancestors, for which 先祖 or 祖先 is the word.
    彼かれの前身ぜんしんについては何なんかご存ぞんじですか。↗
    Are you aware of anything concerning his past life?

For family ancestors use 先祖 or 祖先; 先人 refers respectfully to predecessors and pioneers; 祖 is essentially a combining element, and 前身 means a previous form or existence, not an ancestor.
