Compare with "reproach" in the list for Act 3--the adverbs "severely" and "angrily" make the criticizing tone of a reprimand more unpleasant that that of a reproach. But because the reprimand here is directed at Elizabeth by herself, it is weaker than the reproach that Judge Danforth hears from Reverend Hale.
Elizabeth, with a sense of reprimanding herself for having forgot: Aye!
an unshakable belief in something without need for proof or evidence
Proctor scoffs ("treat with contemptuous disregard") without conviction because as a secret sinner, he does not trust himself or the community. The seventeenth-century Salem court also seems to be scoffing at convictions ("a final judgment of guilty in a criminal case"); normally the accused must be tried and convicted before they are sentenced, but here, those who have been accused must confess their guilt to avoid a death sentence.
Proctor, scoffing, but without conviction: Ah, they’d never hang--
characterized by a firm and humorless belief in the validity of your opinions
A couple of lines later, Proctor shouts: "I cannot speak but I am doubted, every moment judged for lies, as though I come into a court when I come into this house!" This, along with the next two example sentences, connects the Proctors' domestic dispute to a court case (which foreshadows the witch trials and sets up comparisons).
Proctor, with solemn warning: You will not judge me more, Elizabeth.
a signed written agreement between two or more parties (nations) to perform some action
Compare with "covenant" in this list. Although the two are sometimes used interchangeably (both come from words--the Latin "pacisci" and the Old French "convenir"--that mean "to agree"), in the play, "compact" is used both as a noun and verb to refer to an agreement between a human and the Devil. Because a compact is often written and signed, which is necessary when the participants don't trust each other, it is also more appropriate for the Devil.
That she--in horror at the memory--she sometimes made a compact with Lucifer, and wrote her name in his black book--with her blood--and bound herself to torment Christians till God’s thrown down--and we all must worship Hell forevermore
"Monstrous" also means "shockingly brutal or cruel"--both definitions fit, since Abigail would want the abnormally large profit, but Elizabeth would see the profit as shockingly brutal or cruel since it would be gained through her death.
She’d dare not call out such a farmer’s wife but there be monstrous profit in it.
"Glaring" also means "conspicuously and outrageously bad or reprehensible"--both definitions fit (in addition to "glare" as "an angry stare"), since Proctor is describing the physical appearance of golden candlesticks and judging Reverend Parris for spending his hard-earned money on expensive items that add nothing to, and actually hurts, one's spiritual faith.
I labor the earth from dawn of day to blink of night, and I tell you true, when I look to heaven and see my money glaring at his elbows--it hurt my prayer, sir, it hurt my prayer.
a writ from a court commanding police to perform specified acts
"Warrant" also means "formal and explicit approval"--this is the opposite of what Francis is expressing here with his mocking of the words that charge his wife with murder. The warrant also seems to mock itself with the adjective "marvelous" that is supposed to mean "being or having the character of a miracle" but also means "too improbable to admit of belief" and "extraordinarily good or great."
Mockingly quoting the warrant: “For the marvelous and supernatural murder of Goody Putnam’s babies.”
Compare this noun to the adjective "licentious" in the list for Act 1. Lechery is focused on sexual activity and is used here as a punishable crime, while licentious (the Latin "licentia" means "freedom") people simply lack the moral discipline to restrain themselves in any activity that may or may not be a punishable crime.
