I couldn't comprehend the meaning of "pregnant words of poets". Can someone explain this to a non-native english speaker?
"convincing, weighty, pithy," late 14c., "cogent, convincing, compelling" (of evidence, an argument, etc.); sense of "full of meaning" is from c. 1400. According to OED from Old French preignant, present participle of preindre "press, squeeze, stamp, crush," from earlier priembre, from Latin premere "to press, hold fast, cover, crowd, compress" (from PIE root per- (4) "to strike").*

(TIL, for those who'd suspect otherwise. I'm quite a fan of etymology, and Etymology Online in particular.)

(Although I've also heard it used for pauses outside of comedy)
