/ɛr prɪˈzʌmptɪv/ – Phrase
Definition: Người kế thừa dự kiến
A more thorough explanation: 1. someone who seems likely to take over a job or a position when someone else leaves that job or position
2. someone who will, or who seems likely to, inherit property or a title if a person dies at this moment, but whose inheritance may be altered in the future
Example: 1. Princess Elizabeth was by then heir presumptive to the throne.
2. Lachlan – until now generally seen as the heir presumptive – appears to have ruled himself out of the race.
