note
Countable: one separator, two separators. Spelling trap: it is «separ-a-tor» with an «a» in the middle, like «separate» (remember «there is a rat in separate»). In numbers: 1,000 uses a comma as a thousands separator in the UK and USA; 1.5 uses a point as the decimal separator; other countries swap them, so 1.000 may mean one thousand.
