amber   (ām'bər)  Pronunciation Key 

(click for larger image in new window)

A hard, translucent, brownish-yellow substance that is the fossilized resin of ancient trees. It often contains fossil insects.

Our Living Language  : Certain trees, especially conifers, produce a sticky substance called resin to protect themselves against insects. Normally, it decays in oxygen through the action of bacteria. However, if the resin happens to fall into wet mud or sand containing little oxygen, it can harden and eventually fossilize, becoming the yellowish, translucent substance known as amber. If any insects or other organisms are trapped in the resin before it hardens, they can be preserved, often in exquisite detail. By studying these preserved organisms, scientists are able learn key facts about life on Earth millions of years ago.

Amber definition

(Ezek. 1:4, 27; 8:2. Heb., hashmal, rendered by the LXX. elektron, and by the Vulgate electrum), a metal compounded of silver and gold. Some translate the word by "polished brass," others "fine brass," as in Rev. 1:15; 2:18. It was probably the mixture now called electrum. The word has no connection, however, with what is now called amber, which is a gummy substance, reckoned as belonging to the mineral kingdom though of vegetable origin, a fossil resin.
