	Frontispiece In architecture, a frontispiece constitutes the elements that frame and decorate the main, or front, door to a building; especially when the main entrance is the chief face of the building, rather than being kept behind columns or a portico. In books, a frontispiece is an elaborate decorative illustration that appears, either facing the title page of the book, or on the title page itself.
	Frost Frost, like snow, is the result of deposition of water vapor in Saturation air. If solid surfaces in contact with the air are chilled below the deposition point , then spicules of ice grow out from the solid surface. The size of the crystals depends on time and the amount of water vapor available.
	Frostbite Frostbite is the medical condition whereby damage is caused to skin and other biological tissue due to extreme cold. At or below 15 Celsius, blood vessels close to the skin start to narrow. This helps to preserve core body temperature. In extreme cold or when the body is exposed to cold for long periods, this protective strategy can reduce blood flow in some areas of the body to dangerously low levels.

In different forms fruit salad can be served as an appetizer, a side-salad, or a dessert. When served as an appetizer or as a dessert, a fruit salad is also known as a fruit cocktail.
	Fruit tree A fruit tree is a tree bearing fruit — the structures formed by the ripened ovary of a flower containing one or more seeds. However, because all trees of flowering plants produce fruit, the term in horticulture usage applies to trees providing fruit as human food.
	Fruitcake Fruitcake is a heavy cake made of dried or candied fruits and nuts that are soaked in brandy or rum, often used in the celebration of weddings and Christmas.
	Fruiting body In fungi, the fruiting body is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruiting body is part of the sexual phase of a fungal biological life cycle, with the rest of the life cycle being characterized by vegetative mycelium growth.

And while there are varied rumors of Chinese inventing fudge involving a camel, this was a fasley posted rumor put on the internet as a practical joke.
	Fuel Fuel is any material that is capable of releasing energy when its chemical or physical structure is changed or converted. Fuel releases its energy either through chemical means, such as burning, or nuclear means, such as nuclear fission or nuclear fusion. An important property of a useful fuel is that its energy can be stored to be released only when needed, and that the release is controlled in such a way that the energy can be harnessed to produce work.

	Funnel A funnel is a conically shaped pipe, employed as a device to channel liquid or fine-grained substances into containers with a small opening. The diameter of the spout of a regular kitchen funnel is about 1/10 that of the upper bowl. The almost cylindrical tube below the conical upper part that opens into the spout can vary in length.
	Fur The term fur refers to the body hair of non-human mammals also known as the pelage . Fur comes from the coats of animals; the animal's coat may consist of short ground hair, long guard hair, and, in some cases, medium awn hair. Not all mammals have fur; animals without fur may be referred to as "naked", as in The Naked Ape and naked mole rat.
	Fur seal Fur seals make up one of the two distinct groups of mammals called "seals". Both the fur seals and the true seals are members of the Pinnipedia, which is usually regarded as a suborder of the order Carnivora but sometimes as an independent order. However, the fur seals, like their close relatives the sea lions, retain some ability to walk on land as their hind limbs can be brought forward under the body to bear the animal's weight, and retain small but visible external ears.
