Answer key

For grown-ups. Fold this page away before handing over the rest.

False · You never change the root word. Re- just glues onto the front of join: rejoin.
reheat · Re- means 'again,' so reheat means to heat something again.
antivirus · Anti- means 'against,' so an antivirus works against viruses.
Not or opposite · Dis- flips a word to mean 'not' or 'the opposite,' like disagree.
preview · Pre- means 'before,' so preview means to see something ahead of time.
superstar · Super- means 'more than usual,' so a superstar is a star beyond the usual kind.
Washed before they are sold · Pre- means 'before,' so prewash jeans were washed before the shop sold them.
8 · Recharge keeps every letter of re- and charge: 2 + 6 = 8 letters.
He dropped a letter from the root word · Dis- + connect should stay disconnect. Theo dropped one n from connect.
dissatisfy · Both parts keep their own letters: dis ends in s and satisfy starts with s, so dissatisfy has two s's at the seam.
