Hello! I am Studyfin, your learning partner. Today, we will learn how to break down big English words like a detective using Greek and Latin word parts!

Many English words are built from smaller parts called roots, prefixes, and suffixes. The root is the main building block that holds the core meaning. A prefix is added to the beginning of a word, while a suffix is added to the end.

Let us look at how a prefix changes a root word. The Latin root 'port' means to carry. When we add the prefix 'im-' (which means 'into'), we build the word 'import,' which means to carry goods into a country.

im- Prefix (in/into) port Root (to carry) import = to carry into

Now, let us examine how a suffix changes the meaning. The Greek root 'bio' means life, and the suffix '-ology' means the study of. Combining them creates 'biology,' which is the study of living things.

bio Root: Life + -ology Suffix: Study of = biology Study of Life
✏️ Worked example

Determine the meaning of the word 'deconstruct' by analyzing its prefix and root.

  1. Identify the prefix in the word. In 'deconstruct,' the prefix is 'de-'.
  2. Recall the meaning of the prefix. The prefix 'de-' means down, away, or to reverse an action.
  3. Identify the root word. The root is 'struct,' which comes from the Latin word 'struere' meaning to build.
  4. Combine the meanings of the prefix and the root. 'De-' (reverse/down) + 'struct' (build) means to take down what was built.
  5. Formulate the final meaning. 'Deconstruct' means to systematically dismantle or take apart a structure or idea.
