International definition of Plain Language
According to the IPLF:
A communication is in plain language if its wording, structure, and design are so clear that the intended readers can easily find what they need, understand what they find, and use that information.
The Federation is busy developing an ISO Standard for Plain Language (PL). You can read more about this exciting development here: https://www.iplfederation.org/our-work/
The South African legal definition
The South African Consumer Protection Act, 68 of 2008, not only regulates the use of PL, but also defines the concept for a South African context:
Right to information in plain and understandable language
(1) The producer of a notice, document or visual representation that is required, in terms of this Act or any other law, to be produced, provided or displayed to a consumer must produce, provide or display that notice, document or visual representation—
(a) in the form prescribed in terms of this Act or any other legislation, if any, for that notice, document or visual representation; or
(b) in plain language, if no form has been prescribed for that notice, document or visual representation.
(2) For the purposes of this Act, a notice, document or visual representation is in plain language if it is reasonable to conclude that an ordinary consumer of the class of persons for whom the notice, document or visual representation is intended, with average literacy skills and minimal experience as a consumer of the relevant goods or services, could be expected to understand the content, significance, and import of the notice, document or visual representation without undue effort, having regard to—
(a) the context, comprehensiveness and consistency of the notice, document or visual representation;
(b) the organisation, form and style of the notice, document or visual representation;
(c) the vocabulary, usage and sentence structure of the notice, document or visual representation; and
(d) the use of any illustrations, examples, headings, or other aids to reading and understanding.


To summarise the definition: A document is in Plain Language if, and only if, it is clear and understandable for the target audience.
For businesses, the legal definition translates as follows: If your CUSTOMERS experience your communication as clear, relevant, informative, or “exactly what I need”, it is in Plain Language.
