How to say "introduction" in Japanese

• 紹介しょうかいJLPT N4approx.Common
  noun, suru verb, transitive verbThe word for introducing one person to another, or for presenting or showcasing a product or work to others; it also covers referrals. This is what you want for most senses of 'introduction'.

  I want you to meet my parents.
• 導入どうにゅうJLPT N1approx.Common
  noun, suru verb, transitive verbThe introduction of something new into a company or organization — bringing it in, installing it or setting it up, as with a new system or method; it does not mean introducing people.

• 輸入ゆにゅうJLPT N4approx.Common
  noun, suru verb, transitive verbThis is the word for importing goods from abroad; its 'introduction' sense is only that bringing-in-from-outside meaning, so for other senses of 'introduction' it is seldom the word you want.

  Japan's exports exceeded imports by $77.8 billion in 1998.
• 移入いにゅうCommon
  noun, suru verb, transitive verbAn introduction from outside — an import or bringing in of something from elsewhere; it overlaps with 輸入 and is not a word for introducing people to each other.
• 誘いさそいCommon
  nounChiefly an invitation — asking someone to come or join you; its connection to 'introduction' is marginal, so it is seldom the word you want for that sense.

Use 紹介 for introducing people or presenting things, 導入 for bringing in new systems or methods, 輸入 and 移入 only for introducing something from outside, and treat 「誘い」 as an invitation.
