To use ' the ' in front of ' currency ' means that there is more than 1 currency in the US. Logically speaking, it is not right since this is not the case and only 1 single currency applies to 1 country onlyEmotion: smile
There's only one kind of currency and that's the dollar. Then why do we put "the" before "dollar" ?????
Using ' the ' to the dollar to single out this particular unit of currency from among currencies used around the world. In fact, without ' the ' is still acceptable, though because there is no such strong necessity to do so.

eg. Dogs are a faithful animal.

eg. The dogs are a faith animal.

Both are acceptable, the only difference is that the second sentence used to compare dogs with other animals.

You can't omit the first "the" (or "a") in front of "unit" since "unit" is a countable noun in singular form. The same goes for "dollar".

There is no reason (at least none that I can discover) for or against a "the" before "currency". However, the common expression is "the unit of currency".

That said, the words "unit of" are expendable and may even be misleading.


"The dollar is the currency of the US" is 100% accurate.


Technically, the units of currency of the US are dollars and cents. The original sentence ignores cents.
" the dollar " the value of the US dollar, used in comparing the values of different types of money from around the world

The above sentence is from ' Cambridge online dictionary 'Emotion: smile. It seems right that ' the ' is immovableEmotion: smile
