What a learner can do afterwards

  • Identify common Greek and Latin roots in unfamiliar words and use root meaning to infer word meaning, e.g. 'aqua' (water) in aquarium/aquatic, 'dict' (say) in predict/dictionary
  • Break a multi-morpheme word into prefix + root + suffix to determine meaning, e.g. un- (not) + believe + -able = not able to be believed
  • Use knowledge of Greek-origin prefixes (auto-, tele-, micro-) and Latin-origin prefixes (inter-, trans-, sub-) to decode and define unfamiliar vocabulary in context

1 · Read

Many English words are built from small pieces that come from Greek and Latin. If you learn what a few of these pieces mean, you can guess the meaning of words you have never seen before.

trans-port
trans- means across, and port means carry. Put them together: transport means to carry something across a distance.

Here is a small bank of roots to know. aqua means water, as in aquarium. dict means say or tell, as in dictionary. bio means life, as in biology. tele- means far, as in telephone. auto- means self, as in automatic. micro- means small, as in microscope. inter- means between, as in international. sub- means under, as in submarine.

Try it together

Look at the word unbreakable. Split it into three pieces: un- (not) plus break (the root) plus -able (able to be). Put the meanings together and you get: not able to be broken.

un-break-able
Good to know

When you meet a strange word, look for a small piece you already know. That piece is often the clue to the whole word's meaning.

Split an unfamiliar word into its pieces, use the meaning of each Greek or Latin root, and you can often figure out what the whole word means.

Put the two pieces together. What does transport mean?
