How to say "stable" in Japanese

Choosing the right word
  • 堅実けんじつCommon
    na-adjectiveCovers the figurative sense: steady, sound, and safe in the way something is run. Typical of business talk — a company or plan described as stable and dependable rather than risky.
    堅実けんじつな草の根くさのねレベルの運動うんどうを築きずきあげることに集中しゅうちゅうしなければならない。↗
    We must focus on building a solid grass-roots movement.
  • 厩うまやCommon
    nounThe literal building sense: a stable where horses are kept. Use it only for the actual structure; it never covers the figurative senses of 'stable'.
  • 牧舎ぼくしゃCommon
    nounAlso the building sense, but leaning toward 'barn': a structure for keeping and raising livestock in farming contexts. For a horse's stable specifically, 厩 is the more usual word.
  • 強固きょうこCommon
    na-adjectiveCovers 'stable' as firm and solid: something firmly established and hard to shake — a firm stance or solid foundations — rather than calm steadiness over time.
    この実験じっけんで彼かれの学説がくせつはいっそう強固きょうこなものになった。↗
    The experiment confirmed his theory.
