Which root means 'hidden'?

Which root means 'hidden'?

• A. Vas/o
• B. Vesicul/o
• C. Glycos/o
• D. Crypt/o

Answer: (D)

Crypt/o indicates hidden or concealed, coming from the Greek kryptos. In medical terms you’ll see it in cryptorchidism, which describes a testis that remains hidden (undescended) rather than in the scrotum. The other roots point to different concepts: vas/o refers to vessels or the vas deferens; vesicul/o to a vesicle; glycos/o to sugar or glycosides. Since only crypt/o conveys the idea of hidden, it’s the correct root here.
