SAT ROOT FAMILY

SAT Words from the Root dict: 15 Words, Meanings, and Test Examples

A verdict is literally something truly said: vere plus dictum. The Latin root dict (also dic, from dicere, “to say, speak, tell,” and its close relative dicare, “to proclaim”) means “to say.” Fifteen words built on it appear in BARU Vocab’s 3,600-word high-frequency SAT list, from jurisdiction at frequency rank 75 down to vindicate at 3,251. Most of the family is about saying something with authority, which is why so much of it is legal: a court says the law (jurisdiction), a judge declares it (judicial), a jury says what is true (verdict), a ruler says it outward (edict). Every meaning and example below comes from the BARU Vocab dataset; tiers run from 1 (core 1,200 words) to 3 (top-score 800).

How these appear on the digital SAT

Seven of the 15 sit in Tier 1, and those seven rarely show up as the tested blank. They show up as the passage’s own language — a social-science text on sentencing uses jurisdiction and prejudice the way a physics text uses velocity. If you stall on them you lose the paragraph before you reach the question. The words that do get tested are further down the list, and the exam tests the meaning you are least likely to have learned.

Three cases are worth rehearsing. Predicate almost never means the grammar term on this test; it means “to base on,” and it usually arrives as predicated on. Dictate often has no tyrant in it at all — “the geometry of the site dictated the building’s shape” means the site determined it. Vindicate splits two ways: clearing a person of blame, and proving a claim correct. A Reading & Writing passage about a once-dismissed hypothesis uses the second sense, and students who learned only the first pick a wrong answer that feels right.

Where the root stops helping

The letters d-i-c appear in plenty of words that have no connection to speech, and mapping them onto this family will eventually cost you a question. Six common look-alikes:

Looks like dict	Actually from
radical	Latin radix, “root” - the same source as eradicate and ineradicable
ridicule	Latin ridere, “to laugh” - nothing to do with speaking
periodic / sporadic / melodic / nomadic / methodical	Greek endings in -odos or -ikos; the d and the c arrive separately
dichotomy	Greek dikha, “in two”
modicum	Latin modus, “measure”
cowardice	the English suffix -ice, which is not a root at all

A second limit: the root gives you a word's direction, never its register. Dictate, dictum and edict all mean an authoritative saying, yet one is a plain verb, one a quotable maxim, one a decree from a state — and a passage will use that gap to signal who holds power. A root is a compression tool, not a rule.

A 10-minute way to use this list

Cover the meaning column and read only the example sentences. Guess each word from context, then check. That order matters, because the digital SAT tests recognition inside a sentence, not recall from a blank page. Then do one extra pass on the three two-meaning entries — predicate, abdicate, vindicate — saying the less familiar sense out loud. Abdicate is the one to watch: the throne sense is famous, the tested sense is abandoning a duty.
