Par"af*fin, Par"af*fine, n. Etym: [F. paraffine, fr. L. parum too little + affinis akin. So named in allusion to its chemical inactivity.] (Chem.)
Definition: A white waxy substance, resembling spermaceti, tasteless and odorless, and obtained from coal tar, wood tar, petroleum, etc., by distillation. It is used as an illuminant and lubricant. It is very inert, not being acted upon by most of the strong chemical reagents. It was formerly regarded as a definite compound, but is now known to be a complex mixture of several higher hydrocarbons of the methane or marsh-gas series; hence, by extension, any substance, whether solid, liquid, or gaseous, of the same chemical series; thus coal gas and kerosene consist largely of paraffins.
Note: In the present chemical usage this word is spelt paraffin, but in commerce it is commonly spelt paraffine. Native paraffin. See Ozocerite.
– Paraffin series. See Methane series, under Methane.

Contrary to popular belief, coffee beans are not technically beans. They are referred to as such because of their resemblance to legumes. A coffee bean is a seed of the Coffea plant and the source for coffee. It is the pit inside the red or purple fruit, often referred to as a cherry. Just like ordinary cherries, the coffee fruit is also a so-called stone fruit.
