I am often asked about the correct use of capital letters, and particularly whether they make it look like the writer is shouting, or rude.
Of course, we use capital letters for many purposes when we’re writing. We begin sentences with them, we use them to indicate words like proper nouns, to present acronyms, and sometimes to provide emphasis. You will find a comprehensive guide to how to capitalise words in a style guide such as the Oxford style manual or Hart’s rules.
In professionally typeset or designed documents, however, capital letters also have a range of other uses. For example:
The problem with capitals is potentially three-fold. Firstly, it is worth noting the effect that using capitals has on the way we read. Passages Where Almost All the Words Have Initial Capitals will make us apply emphasis to those words. This can make for a very odd reading experience, and in situations where this used to be considered normal practice (such as newspaper headlines, or multiple-word book titles) it is now regarded as old-fashioned, and unnecessary.
It has also been claimed that using capitals for whole words makes them harder to read. The reason for this is disputed. It could be because the same featureless rectangular shape is created by every word, making them harder to identify. Or it could simply be because we are not accustomed to reading words set in capitals. Whatever the reason, presenting short headlines or phrases in capitals is acceptable, but using them for long passages of text should be approached with care.
Finally, the exclusive use of capital letters will undoubtedly create the impression that the writer is shouting. In some situations this may be wholly intentional – a poster advertising a new film may well wish to shout about it. In other situations, such as in emails or other personal communication, however, it can cause offence and in such scenarios, the exclusive use of capitals should be avoided.
Capital letters are also known as ‘majuscules’ or ‘uppercase’. Each of these terms comes from a different era in history.
‘Majuscules’ is generally used in relation to handwritten documents, particularly those created by early scribes. When letterpress printing began in the mid-fifteenth century, the term ‘uppercase’ appeared, referring to the placement of the type case containing the uppercase letters above the one containing the ‘lowercase’ letters.
The term ‘capitals’ originates from Rome, where large-scale inscriptions appear on public buildings and monuments. The words, always in capitals, appear high up on friezes, often across the top of rows of tall columns. In the same way, each column has a top section, which may be ornate or plain, but which is also called a ‘capital’.
