Pro Tips & Tricks

  • Common prefixes: UN- (not), RE- (again), DIS- (opposite), IN-/IM-/IR-/IL- (not), PRE- (before), POST- (after), MIS- (wrongly), OVER- (too much), UNDER- (too little)
  • Common suffixes: -ING (action), -ED (past tense), -ER/-OR (person who), -ABLE/-IBLE (capable of), -TION/-SION (state/action), -NESS (quality), -LY (manner)
  • Spelling rules: Drop final E before adding suffix starting with vowel (MAKE → MAKING)
  • Change Y to I before adding suffix (HAPPY → HAPPINESS, not HAPPYNESS)
  • Double final consonant after short vowel (RUN → RUNNING, but JUMP → JUMPING)
  • Some words change spelling significantly (EXPLAIN → EXPLANATION)

Shortcut Methods to Solve Faster

UN + HAPPY = UNHAPPY
RE + PLAY = REPLAY
DIS + LIKE = DISLIKE
PLAY + ING = PLAYING
READ + ER = READER
LIKE + ABLE = LIKABLE (drop E)
BEAUTY + FUL = BEAUTIFUL (change Y to I)
