The ability to speak or write a language smoothly, accurately, and with ease. In Japanese, this concept is expressed through various terms and phrases depending on whether you are describing general proficiency, natural flow, or specific skills like speaking without hesitation.

流暢 (りゅうちょう) is a more formal term for fluency, often used in writing or official contexts. ペラペラ is casual and onomatopoeic, commonly used in everyday speech to describe someone who speaks a language effortlessly. While both mean 'fluent', ペラペラ can sometimes imply a slightly less formal or academic level of fluency, focusing more on conversational ease.
In English, we often say 'I want to improve my fluency.' In Japanese, it's more natural to use an adjective or verb phrase, e.g., もっと流暢に話せるようになりたい (I want to become able to speak more fluently). Using the noun 流暢さ in such contexts can sound stiff.
