American / British Terms
Both American and British spelling can be found within the Derwent database.
It is important to take this into account when searching in the Topic and Title
fields from the Search page or when using the TS and TI
field tags from the Advanced Search
page. If in doubt as to which spelling to use, search for both options. Example:
tire OR tyre
The list below provides a few examples of some of the differences between
