ده برابر
“ده برابر” (de bârâber) — by an order of magnitude, tenfold in Persian. Phrase, level B1. The learned "by an order" is said here plainly: ten times. A device ten times faster takes its tail. The expenses of the project grew by an order of magnitude, says the example. In a live sentence: “خرج پروژه ده برابر بیشتر شد” — The expenses of the project grew by an order of magnitude. Written with the characters د, ه, ب, ر, ا, ب, ر.

How not to forget this word
Reading a word and remembering it are different jobs. A day later, little survives of a single reading — and that is not bad memory, that is how memory works.
