Did you know?
- The kanji 追 in 追加 literally means 'to chase' or 'to pursue', implying that the addition is following after the original.
- The word 足す (tasu), used for mathematical addition, shares a root with the word for 'foot' (足 – ashi), though they are used very differently in modern Japanese.
- Japanese has a specific word, お代わり, for adding another serving of food or drink, which functions as a noun that 追加する cannot replace.
