Using Word Parts

Many English words are a combination of word parts (prefixes, suffixes and

roots). If you know the meanings of the parts, you can figure out the meanings of the

words that contain these parts.

• the prefix re (meaning again)

• the root juven (meaning young)

• the suffix ate (meaning to make)

• 
  To rejuvenate is “to make young again.”
  

• the root ortho (meaning straight)

• the root dont (meaning tooth, teeth)

• the suffix ist (meaning a person who)

• 
  An orthodontist is “a person who straightens teeth.”
  

base word cannot be divided into parts. (“Base” and “word” are both base words).

However, base words can be combined with other base words, prefixes and suffixes.

Base word + Base word= background, handshake, football

Base word + Prefix = underground, forehand, premeditated

Base word + Suffix = groundless, handful, quickly
