Do we sell customised or customized books? Or is it customise/customize? What is customisation/customization? Read on to find out how to use a word in its adjective, verb and noun forms!
Customise or Customize?
Customise is the original verb form. As British English is the usual standard in Malaysia, we use “customise” rather than “customize” (the American spelling), but either spelling is correct.
Example: How can I customise my book?
Here are two examples of the present tense form:
- How can I customise my book?
- You can customise it at wizardwithin.com.
When to use "customised"?
To use this as an adjective (called the past participle), add -d.
Example: My child loves customised books!
More examples:
- Wizard Within sells customised books.
- I bought a customised book for my child.
- Customised in these examples is used an adjective describing “book”.
For a passive form: Enter three children’s names and the book will be customised for you!
However, customised is not always an adjective. You have to look at the context. It can also be a past tense verb.
When to use "customisation"?
Customisation is a verb turned into a noun. The suffix “-ation” means an action or instance of something or the result or product of an action.
So “customisation” is the act of “customising” or the result of customising.
Example: The customisation is done automatically through our website.
