25 meanings of marker

Practice

  1. 1
    nouncountable or uncountable
    A felt-tipped pen that writes in bold, often permanent ink.

    The teacher uncapped a marker and started filling the whiteboard.

    Permanent markers leave ink that water cannot wash away.

    Similarfelt-tip

    Note

    The sense the whole family grows from: the word is simply mark plus -er, one that makes marks. Felt-tipped pens took the name, and permanent marker is its most familiar pairing, a warning that some ink will not come off a whiteboard. The ink left behind can be called marker, as a mass noun, and the pen also produced a verb.

  2. 2
    nouncountable
    A person or thing that makes marks of any kind.

    Before kickoff, the groundskeeper rolled the marker down the sidelines, leaving a crisp white line behind it.

    Working a step ahead of the loggers, the marker sprayed an orange stripe on every tree that was to come down.

    Note

    The plain sense the specialized ones narrow from: mark plus -er, the ending that turns a verb into whoever or whatever does it. Because that ending names people and tools alike, the same word covers the grader of exams and the felt-tipped pen. Context usually decides which is meant, and the pronoun who removes all doubt: the marker who walks ahead of the loggers is a person, not a spray can.

  3. 3
    nouncountable or uncountable
    An object that marks a place in the landscape, such as a milepost, trail blaze, or surveyor's cairn.

    The surveyor drove a brass marker into the ground at the corner of the lot.

    Old stone markers still line the route the pilgrims once walked.

    Similarpost, landmark, waymark, monument

  4. 4
    nouncountable or uncountable
    A target or goal to work toward, whether a physical point or an abstract achievement.

    Reaching a million users became the startup's next marker.

    Each chapter she finished felt like a marker on the long road to her degree.

    Similarmilestone, goal, target, benchmark

    Note

    The objective sense lives mostly in the idiom put down a marker, meaning to show early and clearly the standard you mean to hold. Phil McNulty, writing for BBC Sport in 2013, used it of a win that put down a marker for how a manager wants his team to play. In use it signals intent more than a goal already reached.

  5. 5
    nouncountable or uncountable
    A spot on a stage or set, usually shown by a small X on the floor, where an actor is to stand or move during a scene.

    The director reminded each actor to find their marker before the take.

    She stepped onto her marker just as the lights came up.

    Similarmark

    Note

    Stage and screen share this spot on the floor, usually an X, and an actor's job is to arrive on it at the right moment. The verbs that go with it are find and step onto. The same word also serves as the call to take positions, so on a set marker can name both the place and the instruction to go there.

  6. 6
    nouncountable or uncountable
    A small counter used to keep score or track position, especially in card games or backgammon.

    She slid her marker forward after rolling the dice.

    The players traded colored markers to settle the round's bets.

    Similarcounter, token, piece, chip

  7. 7
    nouncountable or uncountable
    In genetics, a gene or DNA sequence whose position on a chromosome is known, making it useful for identifying individuals or species.

    Researchers located a marker on the chromosome to trace the inherited trait.

    Comparing genetic markers across populations revealed their shared ancestry.

    Note

    Genetics uses markers as signposts. N Manikanda Boopathi's Genetic Mapping and Marker Assisted Selection (2012) describes markers mapped relative to one another on chromosomes, with genes of interest then found through their linkage to them. The phrase marker-assisted selection captures the working idea: selection guided by a sequence whose position is already known.

  8. 8
    nouncountable or uncountable
    A substance used as an indicator in diagnosis or analysis, also called a biomarker.

    The lab measured a marker that signals liver damage.

    Several markers in the blood sample suggested an infection.

    Similarbiomarker, indicator

    Note

    Medicine's version measures rather than locates: a substance whose presence or level points toward a diagnosis or other finding. Biomarker is the fuller term, and in this sense the two are interchangeable. Do not confuse it with the genetic marker, which is a stretch of DNA identified by its fixed place on a chromosome.

  9. 9
    nouncountable or uncountable
    A defensive player assigned to closely guard one or more opposing attackers.

    The coach assigned his strongest marker to the opposing playmaker.

    Quick markers tracked every run the forwards made.

    Similardefender

    Note

    Sport's defender takes the name from the verb mark, to stay close to an opponent. A forward escapes a marker. Jonathan Jurejko, reporting for BBC Sport in 2012, wrote of Cisse's sharp movement allowing him to escape marker Robert Huth. In that sentence the word sits before the name almost like a title.

  10. 10
    nouncountable or uncountable
    In linguistics, a word or attached word part that signals a grammatical function, such as the -s that marks a plural.

    English adds a marker to show past tense on regular verbs.

    Some languages use separate markers for case and number.

    Note

    In grammar the word means something that carries a function, not a meaning of its own. It can be a free morpheme, which stands as a separate word, or a bound one attached to another word, like the past-tense ending on regular English verbs. Hence tense markers, case markers and number markers. Keep it apart from the short form of discourse marker, which organizes conversation rather than grammar.
