懐妊

1. Origins, structure, and basic meaning

• Structure: 懐妊 is read かいにん and is a relatively formal noun for the state of being pregnant.
• Basic usage: Identify whose pregnancy it is with 妻の懐妊, and make the news the subject in 王妃の懐妊が知らされる.

2. Common pitfalls and similar expressions

• Formal register
  • 懐妊 suits formal contexts such as diaries, historical stories, and accounts involving royalty. It is not required for every everyday mention of pregnancy.
• 懐妊 and 妊娠
  • 妊娠(にんしん) is the general, neutral term for pregnancy. 懐妊 can present the same state in a more formal or celebratory register.
• News and condition
  • 懐妊が知らされる means that news of the pregnancy was announced. It does not mean that the pregnancy began at that moment.
