Expressing zero in English

The amount of nothing or zero can be expressed in many different ways in English. This depends on the context of the sentence.

It can be expressed as: zero, nothing, nought, o, nil.

In sport, we usually say ‘nil’ For example the score was 4-0 (four-nil). However in tennis it is uniquely expressed as ‘love’ (four games to love).

‘O’, pronounced ‘oh’ as in the letter O, is used when talking about times, years, phone numbers (in Britain) and decimals (in Britain)

‘Nought’ is used to talk about the number itself in Britain (but not in America, where zero is used) and phone numbers (Britain)

‘Zero’ is used to talk about the number itself, phone numbers and decimals. Zero is used more often in America, while in Britain we often use ‘o’.

Numbers for money in English

Using English numbers when talking about money requires special treatment. The largest denomination number comes first followed by the currency and finally the smaller denomination number, which can also be followed by the currency.

In everyday speech, people tend to miss out naming the currency if it is obvious which currency they are talking about, especially the smaller denominations (e.g. the pence or cents).

Notice that the decimal point that separates the numbers (e.g. the pounds and pence or dollars and cents) is not pronounced. In English this is written as a decimal point, not a comma like it is in some other European countries, such as Spain.

AMOUNT OF MONEY	PRONOUNCED
£20	twenty pounds (sterling)
$45	forty-five (American) dollars
€250	two hundred and fifty euros
£50.75	fifty pounds, seventy-five pence (‘fifty pounds seventy-five’)
€84.61	eighty-four euros, sixty-one cents (‘eighty-four, sixty-one’)
$103.25	a hundred and three dollars, twenty-five cents

Decimals in English

Decimals in English are written with a full stop (a ‘decimal point’) and this point is spoken aloud when reading the numbers. So you would pronounce 7.5 as ‘seven point five’.

For decimals that are less than 1, such as 0.5, some people pronounce the 0 as ‘nought’ (e.g.  nought point five) while some people do not pronounce the 0 and say simply ‘point five’.

DECIMAL	PRONOUNCED
0.25	(nought) point two five
0.5	(nought) point five
0.75	point seven five
0.05	point zero five / point o five (Britain)
1.834	one point eight three four
4.91	four point nine one
