膨大
ぼうだい
Refers to a quantity or scale that is extremely large. It is a formal na-adjective used in expressions like 「膨大な資料 (an enormous amount of material)」「膨大な費用 (huge expenses)」「膨大なデータ (massive data)」. Rather than physical size, it is often used for quantifiable objects such as volumes of information, amounts of money, or number of items, and frequently carries the nuance that there is 「処理しきれないほど多い (so much it cannot be fully handled)」. While 「莫大」 emphasizes the absolute magnitude of an amount or quantity, 「膨大」 carries a sense of having swollen up through accumulation.
