forever and ever; for all eternity
A literary or formal expression meaning 'for generations without end', often used in poetic, religious, or solemn contexts. Not common in everyday speech.
This love will continue forever and ever.
A tale passed down for all eternity.
Standard kanji spelling using 々 for iteration and 無く for the negative adverbial form.
Variant without the iteration mark; less common but still encountered.
Variant with なく in kana; slightly more modern feel.
Variant with both iteration mark omitted and kana なく.
Compound of 世々 (yoyo, 'generations, ages') + 限り無く (kagirinaku, 'without limit'). The exact historical derivation is uncertain, but it follows a classical pattern of adverbial phrases expressing perpetuity.
