Interest rateAn interest rate is the amount of interest due per period, as a proportion of the amount lent, deposited, or borrowed (called the principal sum). The total interest on an amount lent or borrowed depends on the principal sum, the interest rate, the compounding frequency, and the length of time over which it is lent, deposited, or borrowed. The annual interest rate is the rate over a period of one year. Other interest rates apply over different periods, such as a month or a day, but they are usually annualized.
Trompe-l'œilTrompe-l'œil; trɒmpˈlɔɪ ; tʁɔ̃.p‿lœj) is an artistic term for the highly realistic optical illusion of three-dimensional space and objects on a two-dimensional surface. Trompe l'œil, which is most often associated with painting, tricks the viewer into perceiving painted objects or spaces as real. Forced perspective is a related illusion in architecture. The phrase, which can also be spelled without the hyphen and ligature in English as trompe l'oeil, originates with the artist Louis-Léopold Boilly, who used it as the title of a painting he exhibited in the Paris Salon of 1800.
