Hi there! I am Studyfin, your learning buddy. Today, we will explore how small word parts can change the meaning of a whole word!

Words are like puzzles made of different pieces. A prefix is a word part we add to the beginning of a word. A suffix is a word part we add to the end of a word.

Let us look at the prefix 'mis-'. It means 'badly' or 'wrongly'. If you mismatch your socks, you match them wrongly! The prefix 'sub-' means 'under', like a submarine that travels under the water.

marine sub + marine Sub means under!

Now let us look at suffixes. The suffix '-ment' turns an action word into a noun, like turning 'agree' into 'agreement'. The suffix '-ity' or '-ty' means 'the state of being', like 'activity' or 'safety'.

safe (safe) + -ty (state of) safety (being safe)
✏️ Worked example

Let us figure out the meaning of the word 'misplacement' by breaking it down step by step.

  1. Find the base word. The main word here is 'place', which means to put something somewhere.
  2. Look at the prefix at the beginning. The prefix is 'mis-', which means 'wrongly' or 'badly'.
  3. Look at the suffix at the end. The suffix is '-ment', which means 'the action or result of'.
  4. Combine the parts to find the full meaning. 'Misplacement' means the act of putting something in the wrong place!
