To begin, I have already checked several dictionaries for definitions, such as the one below, from Oxford Living Dictionaries.
secede verb [no object] Withdraw formally from membership of a federal union, an alliance, or a political or religious organization.
'the kingdom of Belgium seceded from the Netherlands in 1830'
‘The only way to prevent this would be to secede from the Union.’
‘If Vermont or Southern California were to secede, a lot of us would join them.’
‘Conversely, a claim of a right to secede from a repressive dictatorship may be regarded as legitimate.’
I found this line in an article today, and wonder whether I am simply missing the intended meaning of the usage. The sentence is from is Trump applauded North Korea's leader after floating the possibility of a 'major, major' conflict in the region, an article on the Business Insider website.
"As the youngest son of Kim Jong Il — the previous leader who died from a heart attack in 2011 — Jong Un seceded his father's place after being heralded as "a great person born of heaven," according to North Korea's state-run media."
Can someone explain whether or not the word 'seceded' is used correctly here? If it is used correctly, an explanation would be very much appreciated.
