Frequently asked questions
Are abbreviations like e.g. handled?
Common abbreviations are recognised so they do not create false sentence breaks, although ambiguous cases still exist in any language.
What is a good average sentence length?
For general web copy, 15–20 words per sentence is comfortable. Technical writing often runs longer, so treat it as a guide.
