    nouncountable or uncountable
    Passage from one side or point to another, whether over, across, or through something.

    The convoy's transit across the desert took three days.

    Heavy snow delayed the climbers' transit over the ridge.

    Similarpassage, crossing, journey

    Note

    The root meaning shows through plainly: French, from Latin transire, "to go across," built from trans "over" and ire "to go." The noun can cross ideas as easily as ground. Edmund Burke wrote in 1790 of France "in the transit from one form of government to another," while Sheridan Le Fanu could speak of "the transit of the wall" for someone's way over it. It usually takes of, across or over.

  3. 3
    nounCanadaUSuncountable
    Shared transportation that members of the public can use for a fare, rather than relying on private cars; a short form of public transit or mass transit.

    Investment in transit helped cut downtown traffic.

    Without good transit, low-income workers struggle to reach jobs.

    Similartransport, transportation

    Note

    A North American usage in which the bare noun, with no article, names the whole system: I always take transit to work, much as one takes the bus. Where British English says public transport, Americans and Canadians often say transit alone. They may also spell it out as public transit or mass transit when the context needs it.

  4. 4
    verbtransitive
    To travel across, over, or through something, such as a region, passage, or body of water.

    Freight trains transit the mountain pass several times a day.

    The expedition transited the frozen strait in record time.

    Similarcross, traverse

    Note

    The verb keeps a single t in its inflected forms: transits, transiting, transited, never transitting. It usually takes the thing crossed as a direct object, so trains transit a pass and expeditions transit a strait, with no preposition needed. Next to cross or pass through, it has a more technical, official sound.

  5. 5
    verbtransitive
    To move passengers or freight from place to place, especially in buses, trains, or other public transportation.

    Ferries transit commuters across the bay each morning.

    The agency transits supplies to remote villages by truck.

    Similartransport, convey, carry, ferry

    Note

    Here the verb becomes causative. Latin transire meant "to go across," but in this use something else is made to go across. The object is the load, not the route: a ferry transits commuters, while in the plain "pass through" meaning a ship transits the canal itself. To tell the two apart, look at what follows the verb. This is also the verb partner of the noun for conveyance.

  6. 6
    nouncountable
    In astronomy, the passage of a celestial body or other object across the face of a larger body, as of Venus across the sun, or across an observer's meridian.

    Astronomers traveled to remote islands to observe the transit of Venus.

    Each transit of the planet across its star dims the light we measure.

    Note

    Astronomy uses the word for two different crossings. A star or planet transits the meridian when it crosses the observer's north–south line, which makes the moment a precise timing mark. A planet or moon transits a disk when it passes in front of a larger body, as Venus does across the Sun. Such crossings were long used to work out longitude and distances in space. The verb is its intransitive partner.

  7. 7
    verbintransitive
    To pass across the disk of a larger celestial body, or across the observer's meridian.

    Venus will transit only once more this century.

    The tiny moon transited across the face of the gas giant.

    Similarpass, cross

    Note

    The verb works without an object: a planet simply transits. If the body or line it crosses is named at all, it follows with across, as in the moon transited across the face of the gas giant. Astronomers use the verb for the same two crossings as the noun, the meridian and the disk of a larger body.

  8. 8
    nouncountable
    An instrument used in surveying to measure angles both horizontally and vertically, much like a theodolite.

    The crew sighted through the transit to mark the property corners.

    An older brass transit still sat in the engineer's field kit.

  9. 9
    nouncountable
    The movement of a celestial body through a section of the horoscope, or in relation to an important point in someone's birth chart.

    She blamed her restlessness on a long Saturn transit.

    A favorable transit through her career sector seemed like the right moment to launch.

    Note

    Here the sky is read against a fixed map: an astrologer's transit is where a planet is now, set against where it stood at someone's birth. That is why transits are named by planet, as in a Saturn transit, and by the section or point of the chart they touch. Nothing need pass in front of anything, unlike the astronomer's transit.

  10. 10
    nounIrelandUKcountable
    A Ford-built panel van, used especially for carrying goods, tools, or a work crew.

    A battered white transit was parked outside the job site all week.

    They squeezed the whole band's equipment into a single transit.

    Note

    A brand name turned common noun in Britain and Ireland, and often written lowercase, as in a road report from Birkenhead of a "white transit" swerving into a junction. It names the van as a type of vehicle rather than a model. Beware the transatlantic clash: an American hearing transit thinks of buses and trains, as in the North American "public transport" sense.

Less common meanings

  1. 11
    verbtransitive
    To rotate a surveying instrument about its horizontal axis so as to reverse the telescope's direction.

    The crew transited the telescope and sighted the line again.

    Surveyors transit the instrument to cancel out small alignment errors.

    Similarplunge

    Note

    A surveyor's verb that belongs with the surveying instrument: the telescope is flipped over on its horizontal axis so that it points the opposite way. Surveyors transit the telescope and then sight the line again. Taking readings in both positions lets small alignment errors in the instrument cancel each other out.

  2. 12
    nouncountable
    An imaginary line between two objects of known position; when a navigator sees one object directly in front of the other, the navigator's position lies along the line.

    The pilot stayed on the transit to keep clear of the shoals.

    A lighthouse and a headland formed a reliable transit into the anchorage.

    Note

    A sailor's way of fixing a line by eye: when a lighthouse sits squarely in front of a headland, the vessel is somewhere on the line running through them. Navigators speak of being on the transit or staying on it. A single transit gives a line, not a point. It tells you where you are across a channel, not how far along it.

  3. 13
    verbtransitive
    To carry another network's or customer's communications traffic to and from third parties for a fee, rather than exchanging it free under a peering arrangement.

    Backbone operators transit traffic for providers that lack global reach.

    Smaller ISPs pay larger ones to transit their data across the world.

    Similarcarry, route, relay

    Note

    A term from the business side of running networks, where the question is who pays. A large network that transits traffic for a smaller one is selling it onward reach to the rest of the Internet, and the customer pays. Two networks that peer instead swap traffic between themselves on equal terms, without charge.
