Words and Latin in this note

Past consideration
Something already done, before the promise and not at the promisor's request. It cannot buy a later promise, unless the act was requested and payment was always expected. Open the note.
Economic duress
Illegitimate commercial pressure that leaves no practical choice. A promise extracted by it may be voidable. Ordinary hard bargaining is not enough. Open the note.
Consideration
The price of a promise: something of value given, or promised, in return. A bare promise to make a gift has none. Open the note.
