Coffee is a brewed drink prepared from roasted seeds, commonly called coffee beans, of the the
plant. They are seeds of cherries that grow on trees in over 70 countries. Green unroasted
coffee is one of the most traded agricultural commodities in the world.[1] Due to its caffeine
content, coffee can have a stimulating effect in humans. Today, it is one of the most popular
beverages worldwide
The first reference to "coffee" in the English language, in the form chaoua, dates to 1598.
In English and other European languages, coffee derives from the Ottoman Turkish kahve, via the Italian
caffè. The Turkish word in turn was borrowed from the Arabic: قهوة, qahwah. Arab lexicographers maintain
that qahwah originally referred to a type of wine, and gave its etymology, in turn, to the verb qahiya,
signifying "to have no appetite", since this beverage was thought to dull one's hunger. Several
alternative etymologies exist that hold that the Arab form may disguise a loanword from an Ethiopian
or African source, suggesting Kaffa, the highland in southwestern Ethiopia as one, since the plant is
indigenous to that area. However, the term used in that region for the berry and plant is bunn,
the native name in Shoa being būn.'
