Practice

  1. 1
    nouncountable
    A tool or machine that removes material to make a hole, usually by pushing a spinning cutting bit into a fixed object.

    The mechanic bored a clean hole through the bracket with a hand drill.

    Modern cordless drills can switch between making holes and driving screws.

  2. 2
    verbtransitive
    To make a hole by removing material with a rotating cutting tool.

    The workers drilled a tunnel through the mountainside.

    You need to drill pilot holes before driving the long screws.

    Similarbore, gouge, excavate

    Note

    Its Middle Dutch source, drillen, meant both "bore" and "move in a circle", which fits a bit that turns as it cuts. That origin is shared by every sense down to the music. The object is usually the hole itself (drill a small hole) rather than the material. Bore is the close synonym. Gouge is the loose one, since gouging scoops material out instead of turning through it.

  3. 3
    nouncountable or uncountable
    An activity done as exercise or practice, especially a military one, to prepare for a possible future event.

    The crew ran through an emergency evacuation drill before the voyage.

    Each drill prepared the recruits for conditions they might face in combat.

    Similarexercise, rehearsal, practice

    Note

    Rehearsal is the point here, and the noun is most at home in compounds that name the emergency being practiced, such as a fire drill. It can also stand before another noun. Joseph C. Lincoln's Mr. Pratt's Patients (1913) has a speaker grumble about being "togged out like a life saver on a drill day."

  4. 4
    verbintransitive
    To practice, especially in a military setting.

    The squad drilled for hours in the pouring rain.

    Cadets drill daily to build discipline and coordination.

    Similartrain, practice

    Note

    Here the learners are the subject, and nobody is named as their trainer: they drilled daily. Add an object, as in the sergeant drilled his troops, and you have its causative partner. The military flavor travels easily into sport. Barney Ronay, writing on Antonio Conte's Chelsea in 2017, notes that a player "wasn't overly drilled" before being moved to right wing-back.

  5. 5
    nouncountable
    A short, highly repeatable training exercise designed to sharpen a particular skill useful in competition.

    The basketball coach ran a dribbling drill before the scrimmage.

    A good footwork drill can improve a player's balance and speed.

    Similarexercise

    Note

    Sport narrows the idea to one skill at a time, repeated until it becomes automatic. These drills usually come in sets and are named by the skill they train, such as goalkeeping drills. The rehearsal sense, by contrast, is named by the event it prepares for, as with a fire drill.

  6. 6
    verbtransitive
    To train others through repeated practice, especially in military skills.

    The instructor drilled the cadets in marching formations.

    Veteran officers drill recruits until every move becomes instinct.

    Similartrain, coach, school, instruct

    Note

    The same verb works in both directions: troops drill, and a sergeant drills them, with no change of form. Grammarians call this pattern ergative. The trained party can reach well beyond soldiers. Thomas Macaulay's Life of Frederick the Great (1859) says Frederick "drilled his people, as he drilled his grenadiers," turning a parade-ground word into a judgment on how a king governed.

  7. 7
    verbtransitive
    To repeat an idea frequently so that someone remembers it.

    The coach drilled the new strategy into the players all week.

    Parents often drill basic manners into their children.

    Similardrum, hammer, instill

    Note

    Into carries the meaning: you drill something into someone, and the idea goes where it is meant to stay. When the idea is long, it moves to the end of the sentence, as in the instructor drilled into us the importance of reading the instructions. That keeps the sentence from stalling. The tone is insistent, closer to relentless repetition than to a gentle reminder.

  8. 8
    verbfigurativelyintransitive
    To investigate or examine something more closely or at a deeper level.

    Analysts drilled down into the regional figures to spot the trend.

    We need to drill into the details before deciding.

    Similardig, delve, probe

    Note

    Boring becomes inquiry. An investigator goes down through layers the way a bit goes through material, and the figure keeps that sense of depth. Deeper is its natural companion, as in drill deeper and the assumptions may turn out faulty. Because the verb needs no object, what is being examined is often left to context.

  9. 9
    nouncountable
    The mechanism in a drilling tool that supplies the force to turn the cutting bit.

    The drill transmits torque to the bit through a tightened chuck.

    A worn motor in the drill will fail to spin the bit at full speed.

    Note

    Workshop speech separates the drill from what it holds: the drill is the body that spins, and the bit is what cuts. Because the drill only drives, it accepts other attachments too, such as a wire brush for stripping rust or buildup. The same tool can therefore clean a surface as readily as bore into it.

  10. 10
    verbtransitive
    To throw, run, hit, or kick something with a lot of power.

    The striker drilled the ball past the diving keeper.

    Quarterbacks drill the football into tight windows between defenders.

    Similarfire, blast, rifle, smash

    Note

    Sportswriters use it for force in a straight line. Joe Coon's The Perfect Game (2006) has a golfer drill the ball "dead center into the hole". Craig Cowell's Muddy Sunday (2007) has a footballer drill it home. The ball is the usual object, followed by where it went. A player can also drill down the court, with the verb carrying the body itself at speed.
