FAQ
Frequently Asked Questions
No, it is an archaic and offensive term when referring to a person. It should be avoided in contemporary usage.
Its primary and overwhelmingly dominant meaning is 'illegitimate child'. An extremely rare, obsolete extension can mean an incidental result, but this is not in active use.
Almost exclusively in historical fiction, older literary texts, or academic works discussing historical social history and family law.
The neutral modern phrase is 'child born out of wedlock' or simply referring to the person without a label. The term 'love child' is a modern, often positive euphemism.
