How to write 40 in words

The number 40 is written “forty” in British English.

40 is one of the basic number words that every larger number is built from, so it has to be learned rather than constructed.

In running text the number is normally lowercase: “the fee is forty pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Forty. Formal documents often give both forms together, for example “forty (40)”, so that a reader can check one against the other.
