詩

1. Origins, structure, and basic meaning

• Structure: 詩 (し) is a noun for a literary work expressing thought or feeling through condensed, often rhythmic language.
• Basic usage: 短い詩を書く makes the composed work the object, while 好きな詩を一編紹介する selects one poem for presentation at a reading.

2. Common pitfalls and similar expressions

• Poem and counter for one work
  • 詩を書く concerns creation in the genre, while 詩を一編 uses 一編 to count one work. The noun is not automatically equivalent to ordinary prose or one song.
