Translation guide
The English word 'effusion' has two main uses: a literal meaning of liquid flowing out (often medical or technical), and a figurative meaning of an unrestrained outpouring of emotion or words. This guide covers both, with Japanese equivalents ranging from medical terms to everyday expressions for emotional gushing.
To describe a medical condition where fluid abnormally accumulates or leaks out, such as pleural effusion or joint effusion.
Medical term for exudation or effusion; refers to fluid that has seeped out of blood vessels into tissues or cavities. Often used in compound words.
Pleural effusion is a condition in which fluid has exuded into the pleural cavity.
Means accumulation or pooling of fluid. Often used in clinical contexts like 'pleural effusion' (胸水貯留). More general than 滲出.
There is an effusion in the joint.
Everyday phrase meaning 'fluid accumulates'. Can be used in non-technical explanations of effusion.
There is fluid accumulating in the lungs.
To describe an outpouring of feelings, often enthusiastic or excessive, such as an effusion of gratitude or poetic effusions.
Literally means 'gushing forth' or 'spurting out', and is used figuratively for a sudden, passionate outburst of emotion or creativity. Often used in literary contexts.
His poetry has an effusion of youthful passion.
Alternate kanji for ほとばしり; same meaning but rarer and more literary. Use ほとばしり in hiragana for broader readability.
Means 'emotions overflow/spill out'. A natural, slightly less intense way to describe an emotional effusion.
Literally 'words filled with heat', used to describe an impassioned speech or effusive language. Suitable for describing someone's effusive praise or declaration.
Japanese often uses mimetic words to describe emotional outpourings. For example, ぽろぽろ (tears flowing) or どっと (bursting out). This can capture the sense of effusion in a vivid, natural way.
Direct translations like 流出 (ryuushutsu, outflow) or 噴出 (funshutsu, eruption) are not used for emotional effusion. They sound unnatural and overly physical. Use the figurative options above instead.
In medical contexts, 滲出 (shinshutsu) specifically refers to exudation due to inflammation. 貯留 (choryuu) is a broader term for fluid accumulation. In everyday speech, 液体が溜まる (ekitai ga tamaru) is more natural.
I cannot suppress the effusion of emotions.
An effusion of gratitude overwhelmed me, and I was at a loss for words.
He expressed his gratitude with an effusion of warm words.
She spoke of her gratitude with an effusion of tears.
