A first look at the origin of the word sovereign reveals a lot:
late 13c., "superior, ruler, master," from Old French soverain "sovereign, lord, ruler," noun use of adjective meaning "highest, supreme, chief"
early 14c., "great, superior, supreme," from Old French soverain "highest, supreme, chief," from Vulgar Latin *superanus "chief, principal", from Latin super "over" (see super-).

(Bold emphases are mine)
However, when we look at covenants and how they were originally intended to work in practise, we see that today's sovereign citizen movement is only partially right. So here is a new definition based on the ancient covenant system:
A sovereign citizen is a man who serves his family as a lord and husband under the Covenant Law of God, to whom he has pledged his oath of covenant love and loyalty.
In principle, he is only answerable to a higher authority within the covenant hierarchy. See also: Trial by JuryMy personal view is that on the whole, men who are sovereign lords over their house(hold) have a strong legal case when they refuse to obey an authority from a different system. However, wisdom is called for when deciding whether to cooperate with a different system on a voluntary basis or not. We live in a fractured society under a patchwork blanket of organisations, authorities, belief systems and religions, and need to have an eye for everyone's wellbeing, not just our own.
