Worth or costing many millions — of dollars, pounds, or whatever money is being talked about. It is an adjective and it almost never stands alone; it lives glued to another word with a hyphen: a multimillion-dollar contract, a multimillion-pound lawsuit, a multimillion-euro fine. If you drop the money word, the sentence usually sounds unfinished to a native ear.

Worth or costing many millions價值或花費達好幾百萬 — of dollars, pounds, or whatever money is being talked about美元、英鎊，或當下在講的任何貨幣。 It is an adjective這是一個形容詞 and it almost never stands alone幾乎不會單獨出現; it lives glued to another word with a hyphen它總是用連字號黏在另一個詞上: a multimillion-dollar contract a multimillion-dollar contract（數百萬美元的合約）, a multimillion-pound lawsuit a multimillion-pound lawsuit（數百萬英鎊的官司）, a multimillion-euro fine a multimillion-euro fine（數百萬歐元的罰款）。 If you drop the money word如果你把貨幣單位那個詞拿掉, the sentence usually sounds unfinished to a native ear在母語人士聽來句子通常會覺得沒講完。

You meet it in news and business writing, where its job is to say 'a very large amount' without giving an exact number — often because the exact number is secret, disputed, or just not the point. That vagueness is deliberate and useful: 'a multimillion-dollar deal' sounds impressive and commits the writer to nothing more precise than 'somewhere above two million'.

You meet it in news and business writing你會在新聞和商業寫作裡遇到它, where its job is to say 'a very large amount' without giving an exact number它的作用是說「一個很大的金額」，卻不給確切數字 — often because the exact number is secret, disputed, or just not the point通常是因為確切數字是秘密、有爭議，或根本不是重點。 That vagueness is deliberate and useful這種模糊是刻意而且有用的: 'a multimillion-dollar deal' sounds impressive「a multimillion-dollar deal」聽起來很厲害 and commits the writer to nothing more precise than 'somewhere above two million'卻沒有讓寫的人承諾比「兩百萬以上的某個地方」更精確的數字。

Notice the number it implies. Multi- means many, so one and a bit million does not qualify; but no one agrees on where the line sits, and writers stretch it freely. Once the figures pass a thousand million, the natural word changes to multibillion.

Notice the number it implies注意它暗示的數字。 Multi- means many Multi- 的意思是「很多」, so one and a bit million does not qualify所以一百多萬不算數; but no one agrees on where the line sits但沒有人真正同意界線在哪裡, and writers stretch it freely寫的人會自由地把它用得很寬。 Once the figures pass a thousand million一旦數字超過十億, the natural word changes to multibillion自然會改用 multibillion 這個詞。

And note the spelling: it is written solid, no hyphen inside the word itself, though the hyphen comes right after when the money word follows.

And note the spelling還要注意拼法: it is written solid, no hyphen inside the word itself這個字本身是連著寫的，中間沒有連字號, though the hyphen comes right after when the money word follows不過後面接貨幣單位的詞時，連字號就緊接在它後面出現。
