嬉しさ

• Reading: うれしさ
• Romaji: ureshisa
• Kanji breakdown: 嬉 (ureshi) — joy, delight; しさ — nominalising suffix (-shisa)
• Pronunciation: /ɯ.ɾe.ɕi.sa/

Meaning

Happiness; joy; delight; gladness. The quality or degree of being pleased or overjoyed by a positive event.

Formed by adding the nominalising suffix さ to the i-adjective 嬉しい (ureshii, happy, glad), converting the state into a measurable quality. It allows speakers to express not just that they are happy but to describe the depth or overflow of that happiness — often used in constructions like 嬉しさのあまり (so overjoyed that...) or 嬉しさで (with joy). More expressive than simply using 喜び.

Examples

1. 合格通知を手にした瞬間の嬉しさは、言葉では表せないほどだった。 The joy she felt the moment she held the acceptance letter was beyond words.
2. 久しぶりに再会した嬉しさのあまり、二人は抱き合った。 Overwhelmed with happiness at reuniting after so long, the two embraced.
3. 思いがけない贈り物を受け取った嬉しさで、彼女の顔がほころんだ。 Her face lit up with delight at receiving the unexpected gift.
