累积

• ピンイン: lěi jī
• 漢字の分解: 累 = 田 + 糸 (layered up/piled); 积 = 禾 + 只 (storing up grain — to accumulate)

意味

（経験などを）蓄積する

Emphasises the gradual process of accumulation, often of abstract things such as experience, data, knowledge, or wealth. The focus is on the ongoing process rather than a final total. Commonly used in academic, scientific, and personal development contexts. Compare 累计, which focuses on the resulting total.
