One way to hold remittance: money travelling from one place to another, with someone waiting at the far end. Nobody hands anything over face to face — it is sent, across a city or across the world.

remittance 可以想成「一筆錢正在路上，另一頭有人在等」。它不是當面把現金交出去，而是隔著距離送過去，可能隔一座城，也可能隔半個地球。這個字有時候指路上的那筆錢，有時候指「送」這個動作，英文用同一個字形。看句子裡加不加 a、有沒有複數，就能分出來說話的人指的是哪一邊。From the word’s history
Remittance is remit plus the ending -ance. Remit carries the idea of sending something off, and -ance turns an action into a noun — so the word can name the sending, and then the thing sent.
remittance 由 remit 加字尾 -ance 造成。remit 帶著「送出去、交付」的意思，-ance 把動作變成名詞。-ance 造出來的名詞常常兩邊都指：既是動作，也是動作的結果。這正好說明為什麼同一個字可以是「匯這件事」，也可以是「匯出去的那筆錢」。
