Possible definitions for portion

motion
Change in position of a body relative to another body or with respect to a frame of reference or coordinate system. Motion occurs along a definite path, the nature of which determines the character of the motion. Translational motion occurs if all points in a body have similar paths relative to another body. Rotational motion occurs when any line on a body changes its orientation relative to a line on another body. Motion relative to a moving body, such as motion on a moving train, is called relative motion. Indeed, all motions are relative, but motions relative to the earth or to any body fixed to the earth are often assumed to be absolute, as the effects of the earth's motion are usually negligible. See also Brownian motion, harmonic motion, periodic motion, simple motion, uniform circular motion.


Orion
In Greek mythology, a powerful hunter. He was sometimes said to be the son of Poseidon. He drove the wild beasts out of the island of Chios and fell in love with Merope, daughter of the king. Disapproving of Orion, the king had him blinded, but his vision was restored by the rays of the rising sun. He later went to Crete to live and hunt with Artemis. Some legends hold that he was killed by Artemis or Apollo out of jealousy; another tells that he was fatally bitten by a scorpion. After his death the gods placed him in the sky as a constellation.


portico
Colonnaded porch or entrance to a structure, or a covered walkway supported by regularly spaced columns. The portico is a principal feature of Greek temple architecture and thus a prominent element in Roman and all subsequent Classically inspired structures.

It was the birthplace of H. W. Longfellow.

Settled in 1829 on the site of an early Indian campground, it was laid out in 1844 and incorporated in 1851. Early growth was stimulated by gold rushes and the flow of immigrants along the Oregon Trail. It is the state's largest city and principal port. Exports include lumber, aluminum, and wheat. Shipbuilding and meat-packing are important industries. It is the site of many educational institutions, incl. Lewis and Clark College (1867) and Reed College.
