Full list of words from this list:

  1. impervious
    not admitting of passage or capable of being affected
    The fact that Harry Potter was going out with Ginny Weasley seemed to interest a great number of people, most of them girls, yet Harry found himself newly and happily impervious to gossip over the next few weeks.
  2. jocular
    characterized by jokes and good humor
    He had not dared to return to the Room of Requirement to retrieve his book, and his performance in Potions was suffering accordingly (though Slughorn, who approved of Ginny, had jocularly attributed this to Harry being lovesick).
  3. sullen
    showing a brooding ill humor
    She was not pretty; she looked simultaneously cross and sullen, with heavy brows and a long, pallid face.
  4. vouchsafe
    grant in a condescending manner
    “Professor, were you trying to get into the Room of Requirement?”
    “...omens I have been vouchsafed — what?” She looked suddenly shifty.
    “The Room of Requirement,” repeated Harry. “Were you trying to get in there?”
  5. intimate
    give to understand
    “The headmaster has intimated that he would prefer fewer visits from me,” she said coldly.
  6. bandy
    discuss lightly
    Perhaps the horse has heard people say that I have not inherited my great-great-grandmother’s gift. Those rumors have been bandied about by the jealous for years.
  7. uncouth
    lacking refinement or cultivation or taste
    Yes, there was a commotion outside the door and it flew open, and there was that rather uncouth barman standing with Snape, who was waffling about having come the wrong way up the stairs...
  8. unassuming
    not arrogant
    "...Dumbledore seemed much more disposed to give me a job, and I could not help thinking, Harry, that it was because he appreciated the stark contrast between my own unassuming manners and quiet talent, compared to the pushing, thrusting young man who was prepared to listen at keyholes..."
  9. sentry
    a person employed to keep watch for some anticipated event
    She looked alarmed as he ran past her, around the corner into Dumbledore’s corridor, where the lone gargoyle stood sentry.
  10. mirth
    great merriment
    Harry let out a yell of mirthless laughter.
  11. hamper

    It was a treacherous descent and Dumbledore, hampered slightly by his withered hand, moved slowly.
  12. fissure
    a long narrow opening
    Harry saw a fissure in the cliff into which dark water was swirling.
  13. oppressive
    weighing heavily on the senses or spirit
    Harry found the place and the silence oppressive, unnerving.
  14. unqualified
    not meeting the proper standards and requirements
    “I do not think you will count, Harry: You are underage and unqualified. Voldemort would never have expected a sixteen-year-old to reach this place: I think it unlikely that your powers will register compared to mine.”
  15. cleave
    separate or cut with a tool, such as a sharp instrument
    There was no sound other than the silken rustle of the boat’s prow cleaving the water; it moved without their help, as though an invisible rope was pulling it onward toward the light in the center.
  16. inexorably
    in a manner impervious to change or persuasion
    He turned his head to look at the greenish glow toward which the boat was still inexorably sailing.
  17. phosphorescent
    emitting light without appreciable heat
    The basin was full of an emerald liquid emitting that phosphorescent glow.
  18. render
    cause to become
    “Undoubtedly,” he said, finally, “this potion must act in a way that will prevent me taking the Horcrux. It might paralyze me, cause me to forget what I am here for, create so much pain I am distracted, or render me incapable in some other way. This being the case, Harry, it will be your job to make sure I keep drinking, even if you have to tip the potion into my protesting mouth. You understand?”
  19. agape
    with the mouth wide open as in wonder or awe
    “No!” shouted Harry, who had stood to refill the goblet again; instead he dropped the cup into the basin, flung himself down beside Dumbledore, and heaved him over onto his back; Dumbledore’s glasses were askew, his mouth agape, his eyes closed.
  20. crevice
    a long narrow opening
    They crossed the outer cave, and Harry helped Dumbledore back into the icy seawater that filled the crevice in the cliff.
  21. stimulant
    a drug that temporarily quickens some vital process
    As they sped toward the castle, Harry glanced sideways at Dumbledore, ready to grab him should he fall, but the sight of the Dark Mark seemed to have acted upon Dumbledore like a stimulant: He was bent low over his broom, his eyes fixed upon the Mark, his long silver hair and beard flying behind him on the night air.
  22. rampart
    an embankment built around a space for defensive purposes
    Dumbledore had already crossed the crenellated ramparts and was dismounting; Harry landed next to him seconds later and looked around.
  23. vehemently
    in a forceful manner
    “It has been in it!” said Malfoy vehemently. “I’ve been working on it all year, and tonight—”
  24. limbo
    an imaginary place for lost or neglected things
    Montague told me that when he was stuck in the Hogwarts one, he was trapped in limbo but sometimes he could hear what was going on at school, and sometimes what was going on in the shop, as if the cabinet was traveling between them, but he couldn’t make anyone hear him…
  25. gratify
    make happy or satisfied
    “Very gratifying,” said Dumbledore mildly. “We all like appreciation for our own hard work, of course..."
  26. buffet

    But suddenly footsteps were thundering up the stairs, and a second later Malfoy was buffeted out of the way as four people in black robes burst through the door onto the ramparts.
  27. unscathed
    not injured
    The dimly lit corridor was full of dust; half the ceiling seemed to have fallen in; and a battle was raging before him, but even as he attempted to make out who was fighting whom, he heard the hated voice shout, “It’s over, time to go!” and saw Snape disappearing around the corner at the far end of the corridor; he and Malfoy seemed to have forced their way through the fight unscathed.
  28. fray
    a noisy fight
    As Harry plunged after them, one of the fighters detached themselves from the fray and flew at him: It was the werewolf, Fenrir.
  29. parry
    impede the movement of
    But Snape parried the curse, knocking Harry backward off his feet before he could complete it; Harry rolled over and scrambled back up again as the huge Death Eater behind him yelled, “Incendio!”
  30. inarticulate
    without or deprived of the use of speech or words
    Harry uttered an inarticulate yell of rage: In that instant, he cared not whether he lived or died.
  31. suffuse
    become overspread as with a fluid, a color, or light
    Snape’s pale face, illuminated by the flaming cabin, was suffused with hatred just as it had been before he had cursed Dumbledore.
  32. inert
    unable to move or resist motion
    Fear stirred in Harry’s chest again: He had forgotten the inert figures he had left behind.
  33. ironclad
    inflexibly entrenched and unchangeable
    “He always hinted that he had an ironclad reason for trusting Snape,” muttered Professor McGonagall, now dabbing at the corners of her leaking eyes with a tartan-edged handkerchief.
  34. explicitly
    in a clearly expressed manner
    “I mean...with Snape’s history...of course people were bound to wonder...but Dumbledore told me explicitly that Snape’s repentance was absolutely genuine...Wouldn’t hear a word against him!”
  35. duplicity
    the act of deceiving or acting in bad faith
    “So when he arrived at the fight, he joined in on the Death Eaters’ side?” asked Harry, who wanted every detail of Snape’s duplicity and infamy, feverishly collecting more reasons to hate him, to swear vengeance.
  36. infamy
    a state of extreme dishonor
    “So when he arrived at the fight, he joined in on the Death Eaters’ side?” asked Harry, who wanted every detail of Snape’s duplicity and infamy, feverishly collecting more reasons to hate him, to swear vengeance.
  37. traipse
    walk or tramp about
    “Rosmerta?” said Professor McGonagall incredulously, but before she could go on, there was a knock on the door behind them and Professors Sprout, Flitwick, and Slughorn traipsed into the room, followed by Hagrid, who was still weeping copiously, his huge frame trembling with grief.
  38. assent
    agreement with a statement or proposal to do something
    “I suppose...yes..." said Slughorn in a rather agitated voice, while Hagrid let out a strangled sob of assent.
  39. mantra
    a commonly repeated word or phrase
    This mantra seemed to pulse through Harry’s mind as he fell asleep at night, and his dreams were thick with cups, lockets, and mysterious objects that he could not quite reach, though Dumbledore helpfully offered Harry a rope ladder that turned to snakes the moment he began to climb...
  40. unwonted
    out of the ordinary
    Ron gave no sign that he was aware of Percy, apart from stabbing pieces of kipper with unwonted venom.
  41. animosity
    a feeling of ill will arousing active hostility
    His animosity was all for Snape, but he had not forgotten the fear in Malfoy’s voice on that tower top, nor the fact that he had lowered his wand before the other Death Eaters arrived.
  42. discernible
    perceptible by the senses or intellect
    The castle ghosts were there too, barely visible in the bright sunlight, discernible only when they moved, shimmering insubstantially on the gleaming air.
  43. sentinel
    a person employed to keep watch for some anticipated event
    At the sight of the centaur Firenze, who was standing like a sentinel near the water’s edge, she gave a start and scurried hastily into a seat a good distance away.
  44. eradicate
    destroy completely, as if down to the roots
    It was important, Dumbledore said, to fight, and fight again, and keep fighting, for only then could evil be kept at bay, though never quite eradicated...
  45. delicacy
    subtly skillful handling of a situation
    Scrimgeour hesitated, then said, in what was evidently supposed to be a tone of delicacy, “The Ministry can offer you all sorts of protection, you know, Harry. I would be delighted to place a couple of my Aurors at your service—”
