Dear participants in the open global table,
 I hope you will value this definition submitted by another attendee 

Usury has only one lawful definition detailed in Black’s law dictionary: Usury is a certain benefit which is received for the use of the thing lent beyond the return in full of the thing lent, and is not lawful. So the simple reality of usury is corrupted and confused, to allow those who wish to steal, to hide their thefts from their victims.
Usury is a benefit from a loan of a thing, so if I loan you a house and you return the house to me in the same condition as it was borrowed, that is fair, but if I demanded a benefit of rent that would be usury. The most that could be demanded would be the loss in depreciation of the labours invested in the object loaned.

Trade is the reciprocal exchange of the fruits of my labour for the fruits of someone else’s labour. Usury (riba) is not trade.

Usury is a one-sided extraction of the fruits of the labours of another, which has 5 basic forms:
• Debt (the interest demand for the use of money)
• Profit (the interest demanded for the use of capital)
• Rental (the interest demanded for the use of infrastructure)
• Taxation (the interest demanded for the use of your labour)
• Ownership (the interest demanded for the use of land through the fiction of eminent domain)
