Usage Note: To indicate motion toward a position, both on and onto can be used: The cat jumped on the table. The cat jumped onto the table. Onto is more specific, however, in indicating that the motion was initiated from an outside point. He wandered onto the battlefield means that he began his wandering at some point off the battlefield. He wandered on the battlefield may mean that his wandering began on the battlefield. · In constructions where on is an adverb attached to a verb, it should not be joined with to to form the single word onto: move on to (not onto) new subjects; hold on to (not onto) our gains. · In their uses to indicate spatial relations, on and upon are often interchangeable: It was resting on (or upon) two supports. We saw a finch light on (or upon) a bough. To indicate a relation between two things, however, instead of between an action and an end point, upon cannot always be used: Hand me the book on (not upon) the table. It was the only town on (not upon) the main line. Similarly, upon cannot always be used in place of on when the relation is not spatial: He wrote a book on (not upon) alchemy. She will be here on (not upon) Tuesday.

abbr.

Old Norse
Ontario

On·tar·i·o (ŏn-târ'ē-ō')

Abbr. ON or Ont. A province of east-central Canada. It joined the confederation in 1867. First visited by French explorers in the early 1600s, it passed to the British in 1763 and became part of the province of Quebec in 1774. It was called Upper Canada after its division from Quebec (then Lower Canada) in 1791. Reunited with Lower Canada in 1841, it became a separate province with the formation of the confederation. Toronto is the capital and the largest city. Population: 12,200,000.
A city of southern California east of Los Angeles. It is a residential and industrial center in a citrus-growing region. Population: 173,000.

Word Origin & History

O.E. on, unstressed variant of an "in, on, into," from P.Gmc. (cf. Du. aan, Ger. an, Goth. ana "on, upon"), from PIE base *ano "on" (cf. Avestan ana "on," Gk. ana "on, upon," L. an-, O.C.S. na, Lith. nuo "down from"). Also used in O.E. in many places where we would now use in. From 16c.-18c. (and still in northern England dialect) often reduced to o'. Phrase on to "aware" is from 1877.

Bible Dictionary

On

light; the sun, (Gen. 41:45, 50), the great seat of sun-worship, called also Bethshemesh (Jer. 43:13) and Aven (Ezek. 30:17), stood on the east bank of the Nile, a few miles north of Memphis, and near Cairo, in the north-east. The Vulgate and the LXX. Versions have "Heliopolis" ("city of the sun") instead of On in Genesis and of Aven in Ezekiel. The "city of destruction" Isaiah speaks of (19:18, marg. "of Heres;" Heb. 'Ir-ha-heres, which some MSS. read Ir-ha-heres, i.e., "city of the sun") may be the name given to On, the prophecy being that the time will come when that city which was known as the "city of the sun-god" shall become the "city of destruction" of the sun-god, i.e., when idolatry shall cease, and the worship of the true God be established. In ancient times this city was full of obelisks dedicated to the sun. Of these only one now remains standing. "Cleopatra's Needle" was one of those which stood in this city in front of the Temple of Tum, i.e., "the sun." It is now erected on the Thames Embankment, London. "It was at On that Joseph wooed and won the dark-skinned Asenath, the daughter of the high priest of its great temple." This was a noted university town, and here Moses gained his acquaintance with "all the wisdom of the Egyptians."
