Accents

Accents are a kind of diacritic mark used to show the pronunciation or stress in a word. Examples include the acute mark (frappé), umlaut (naïve), circumflex (paper-machê), tilde (señor) and cedilla (façade).

Accents are most common when using words from a non-English language.

Over time, words imported into English from other languages tend to lose their accents. So the first question is whether to use accents at all when writing in English.

The ASG recommends minimising their use, as long as the meaning is clear to your intended audience. Accents can be difficult to format and are prone to error when copying and pasting text.

However, if you think keeping the accents will help readers make sense of the word and its pronunciation, you can do so. And keep them on the names of people or organisations.

Some style guides argue that you need accents to differentiate between words that are spelt the same way but have different meanings and pronunciation.

However, in most cases the context will usually make the meaning clear without an accent. On a wine list, for example, you're unlikely to expect a glass of flowers if you order from the Rose rather than the Rosé list.

That said, on the rare occasion that identically spelled words of different meaning appear together in a sentence, you will need to take care if you can’t rephrase.
