Here are some inner workings of the world: -Umami is a proposed addition to the currently accepted four basic tastes sensed by specialized receptor cells present on the human tongue. Umami is a Japanese word meaning savory, a "deliciousness" factor deriving specifically from detection of the natural amino acid, glutamic acid, or glutamates common in meats, cheese, broth, stock, and other protein-heavy foods. The action of umami receptors explains why foods treated with monosodium glutamate (MSG) often taste "heartier".
-Mail-order bride is a label applied to a woman who publishes her intent to marry someone from another - usually more developed - country. Although the label is widely used, it may have derogatory connotations and may be offensive.
Historically, mail-order brides were women who listed themselves in catalogs and were selected by men for marriage. Sometimes the men and women involved were citizens of different countries, e.g. women from European countries moving to the United States during the 18th and 19th centuries, and sometimes they involved citizens of the same country. Mail-order brides traditionally hail from developing countries, major examples being Colombia, Venezuela, Thailand and to a lesser extent from Mexico, Philippines, Vietnam, India, China and Malaysia. Since the collapse of the Soviet Union, however, large numbers of eastern European women also advertised themselves in such a way; primarily being from Russia, Ukraine and Moldova. In the past, international marriage agencies such as Cherry Blossoms allowed women to sign up to be listed in picture magazines; now the Internet has largely supplanted this method. Men who list themselves in such publications may be referred to as mail-order husbands. Nations that often receive mail-order brides are the United States, Canada, United Kingdom, South Korea, Taiwan, Germany, and Australia.
-A corner is the place where two lines of different dimensions meet at an angle, and a convex corner of intersecting walls is generally thought to be the least beneficial position to be in a life-or-death situation. From this notion was born the verb to corner, which is used to mean "To back (another person or animal) into a corner" and usually also carries a connotation of foul play.
In square dance, corner refers to the person you are adjacent to who is not your partner. In standard positioning (boy on the left, girl on the right), this would be for men (or gents) the person standing to one's left, and for ladies the person standing to one's right. In square dance one will often change partners and corners during the course of a dance, in which case one can distinguish between the "original corner" and a "situational corner".
-Hyperdontia is the condition of having supernumerary teeth, or teeth which appear in addition to the regular number of teeth. The most common supernumerary tooth is a mesiodens, which is a mal-formed, peg-like tooth that occurs between the maxillary central incisors. Fourth and fifth molars that form behind the third molars are another kind of supernumerary teeth. Another rare type of supernumerary teeth is a "third set of teeth" that forms underneath and pushes out the second set of teeth, much like the second set formed underneath and pushed out the first set of teeth.
