Learning
Memory Aids
Mnemonic
Think of 'Quine' rhyming with 'shine'. A quine program makes its own code shine by outputting it.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with the common Russian name 'Квин' (Kvin) or the English word 'queen'.
- It is a technical term with no direct common equivalent; a descriptive translation like 'самовоспроизводящаяся программа' is needed.
Common Mistakes
- Misspelling as 'queen' or 'quiene'.
- Using it as a general term for any recursive function.
- Pronouncing it /kwiːn/ like 'queen' instead of /kwaɪn/.

The American philosopher and logician Willard Van Orman Quine (1908–2000).
No, in standard usage it is only a noun. The act is described as 'writing a quine' or 'quining' is non-standard jargon.
It is primarily a conceptual exercise and puzzle in programming theory to demonstrate self-reference and metaprogramming techniques.
