A tautology is a phrase or expression in which the same thing is said twice in different words. Don’t use them – they’re considered to be a fault of style.

Common examples include:

Advance warning
Fixed phone line  Pre-planned
 Anti-government rebel forces  Local resident  Sharia law (Sharia means Islamic religious law)
  Armed gunmen  Mutual co-operation  Universal panacea
 Crew members  Past history  Weather conditions 
 Exact replica  Pre-conditions  

As a general rule, "that" defines, and "which" informs.

What does that actually mean?

So, in the sentence, “The house that Jack built is to be knocked down”, the phrase “that Jack built” is included to differentiate his house from a group of houses.

Imagine four houses – one built by Jack, and one each by Jill, the Three Little Pigs, and Wimpey. Of those four houses, only one is to be knocked down – the house that Jack built. “That”, in this sentence, defines which house we are talking about – which of the four houses will be knocked down.

In comparison, “The house, which Jack built, is to be knocked down”, assumes we know exactly which house we’re talking about. The fact that Jack was the builder is the new information. So, the phrase, "which Jack built", gives us additional information – it informs.

Use this format:

  • Day, date, month and then year, for example, Monday 15 January 2019
  • Show times using a 24-hour clock, for example, 21:00 or 17:00

Include the day, time and venue for forthcoming events, and when advertising an event for an international audience, such as an Online Open Day, state the time zone as well as the time. For example, 14:00-16:00 (BST).

Don’t use ordinal indicators – the superscripted -st, -nd, -rd, and -th following the day number. For example, write 15 January and not 15th January.

Titles and headers within the body copy of a page are all in sentence case, Not First Word Capitalised or ALL IN CAPITALS.

Where it’s appropriate to use capitalisation in titles and headers, this has already been built into the content management system (CMS) of our website. So, when adding titles, headings and subheadings, always apply sentence case.

This aids accessibility and readability. It’s also less jarring for people who didn’t grow up speaking English.
