Hard SAT Words Explained: Definitions, Examples, and Memory Tricks

A breakdown of the hardest SAT vocabulary words — what they mean, how they're used, and how to actually remember them.

Some SAT words are genuinely hard. They look obscure, they're rarely used in everyday speech, and a paper flashcard can't really teach them. Below are ten of the hardest words that appear on the SAT, broken down clearly.

Hard Word Breakdown

  • Acquiesce — to agree reluctantly. Example: He acquiesced to her demands.
  • Capricious — sudden, unpredictable change. Example: A capricious boss who changes plans hourly.
  • Loquacious — extremely talkative. Example: Her loquacious uncle dominated dinner.
  • Ephemeral — short-lived. Example: Cherry blossoms are ephemeral.
  • Ubiquitous — everywhere at once. Example: Smartphones are ubiquitous.
  • Aberration — something out of the norm. Example: A snowy day in July is an aberration.
  • Austere — plain and strict. Example: The austere room had only a desk.
  • Abate — to reduce. Example: The fever finally abated.
  • Tenacious — refusing to give up. Example: A tenacious crab clings to a rock.
  • Verbose — wordy. Example: His verbose emails are exhausting.

Memory Tricks That Work

Tie hard words to root meanings (loqu = speak, bene = good, mal = bad) and to vivid mini-images. LearnLexiq does both automatically — root analysis is built into every card.
