Dictionary.com's Word of the Year is...
"young cow," Old English cealf (Anglian cælf) "young cow," from West Germanic *kalbam (cf. Middle Dutch calf, Old Norse kalfr, German Kalb, Gothic kalbo), perhaps from PIE *gelb(h)-, from root *gel- "to swell," hence, "womb, fetus, young of an animal." Elliptical sense of "leather made from the skin of a calf" is from 1727. Used of icebergs that break off from glaciers from 1818.
fleshy part of the lower leg, early 14c., from Old Norse kalfi, source unknown; possibly from the same Germanic root as calf (n.1).
n. pl. calves (kāvz)
The fleshy, muscular back part of the human leg between the knee and ankle, formed chiefly by the bellies of the gastrocnemius and soleus muscles.
Calves were commonly made use of in sacrifices, and are therefore frequently mentioned in Scripture. The "fatted calf" was regarded as the choicest of animal food; it was frequently also offered as a special sacrifice (1 Sam. 28:24; Amos 6:4; Luke 15:23). The words used in Jer. 34:18, 19, "cut the calf in twain," allude to the custom of dividing a sacrifice into two parts, between which the parties ratifying a covenant passed (Gen. 15:9, 10, 17, 18). The sacrifice of the lips, i.e., priase, is called "the calves of our lips" (Hos. 14:2, R.V., "as bullocks the offering of our lips." Comp. Heb. 13:15; Ps. 116:7; Jer. 33:11). The golden calf which Aaron made (Ex. 32:4) was probably a copy of the god Moloch rather than of the god Apis, the sacred ox or calf of Egypt. The Jews showed all through their history a tendency toward the Babylonian and Canaanitish idolatry rather than toward that of Egypt. Ages after this, Jeroboam, king of Israel, set up two idol calves, one at Dan, and the other at Bethel, that he might thus prevent the ten tribes from resorting to Jerusalem for worship (1 Kings 12:28). These calves continued to be a snare to the people till the time of their captivity. The calf at Dan was carried away in the reign of Pekah by Tiglath-pileser, and that at Bethel ten years later, in the reign of Hoshea, by Shalmaneser (2 Kings 15:29; 17:33). This sin of Jeroboam is almost always mentioned along with his name (2 Kings 15:28 etc.).
