Choosing the right word

    The distinction in usage between the two words is clear.
  • 体節動物たいせつどうぶつ
    nounA zoological noun, not an adjective: it names an articulate animal in the biological sense — an arthropod or an annelid — and has nothing to do with clear speech.
  • nounThe English word borrowed as-is in katakana. It keeps the feel of the foreign term, and it is seldom the natural way to say 'articulate' unless the English word itself is wanted.
  • 平明達意へいめいたつい
    nounA four-character idiom meaning plain and lucid, used of speech or writing that clearly gets its point across; it fits 'articulate' as an evaluation of how well someone expresses things.
  • 事細かいことこまかい
    i-adjectiveAn adjective for accounts or explanations that go into every detail; as a rendering of 'articulate' it covers only the minute-detail nuance, not the sense of speech that is clear and easy to follow.

Choose 明瞭 for clear, distinct speech or sound; 平明達意 for lucid, plain expression; 「事細かい」 for minute detail; 体節動物 for the zoological sense; 「アーティキュレート」 only as the borrowed English term.
