Seventy-Three in Numbers

How to write 73 in words

The number 73 is written “seventy-three” in British English. The hyphen in seventy-three is not optional – every compound number from twenty-one to ninety-nine is hyphenated.

73 is one of the basic number words that every larger number is built from, so it has to be learned rather than constructed – but remember the hyphen between the tens and the units.

In running text the number is normally lowercase: “the fee is seventy-three pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Seventy-Three. Formal documents often give both forms together, for example “seventy-three (73)”, so that a reader can check one against the other.

How to write 73 on a cheque

Banks read the amount in words as the legal amount, so it must be exact. Write the pounds in words, add the word pounds, and finish with only so that nothing can be added afterwards.

• With pence: add the pence after the pounds – “Seventy-three pounds and fifty pence only” for £73.50 – or write the pence as a fraction, “Seventy-three pounds 50/100”.
• US check: “Seventy-three and 00/100 dollars”. American cheques drop the “and” after the hundreds and put it before the cents.
• Bangladesh, India and Pakistan: the currency word comes first and the amount is counted in lakh and crore – “Taka seventy-three only”, with the figure written Tk. 73/=.

73 in British and American English

73 in Bangla (বাংলায় ৭৩)

In Bangla, 73 is written ৭৩ using Bengali digits, and in words it is তিয়াত্তর. Bangla has its own word for every number from one to ninety-nine, and above that it counts in হাজার (thousand), লাখ (lakh) and কোটি (crore), the same grouping used across Bangladesh and India.

On a cheque or invoice written in Bangla the amount reads তিয়াত্তর টাকা মাত্র (“তিয়াত্তর taka only”). In English on the same cheque it is Taka seventy-three only – see How to write a cheque in Bangladesh.

Common mistakes when writing 73

• Missing the hyphen. seventy three is a very common misspelling. Write seventy-three.
• Mixing words and figures. In running text keep to one style: seventy-three or 73, not 73 (seventy-three) unless it is a legal document.
