Frequently Asked Questions
What is a word stem (root)?
A word stem — like “spect” (to look) or “port” (to carry) — is the core of a word that carries its meaning. Learn one root and you can decode dozens of words built from it, like inspect, respect, and spectacular.
Is Stem Cards good for SAT or GRE prep?
Yes. Standardized tests love words built from Latin and Greek roots. Knowing roots lets you decode unfamiliar words on test day instead of guessing.
Do I need to already know English well?
Stem Cards works best if you have basic English and want to grow your vocabulary faster — it’s a complement to core study, not a replacement.
Is Stem Cards free?
Yes, Stem Cards is free.
How is this different from regular flashcards?
Regular flashcards teach you one word at a time. Stem Cards teaches you the building blocks — learn 100 roots and you can decode thousands of words.
