- The word アルカリ is a phonetic borrowing of the Arabic word 'al-qaly', which refers to plant ashes used to make soap. It entered Japanese via Western chemistry rather than directly from Arabic.
- The opposite of アルカリ性, which is 酸性 (acidic), contains the character for 'sour' (酸). This connects the abstract chemical concept of acidity directly to the physical taste of things like lemons.
- In Japanese health and wellness trends, 'alkaline water' is often called アルカリイオン水 (alkaline ion water). This specific phrasing is used to highlight the technology used to produce the water rather than just its pH level.
