    Common Mistakes

    1. The prefix in- does not have a negative meaning always. It often means ‘inside’ or ‘into’, for instance, internal, income, and insert.
    2. The antonym of a word must be exactly the same part of the speech as that particular word.
    3. Examples:

      1. Adjective – Antonym – (good-bad)
      2. Verb – Antonym – (hate - love)
      3. Noun – Antonym – (strength-weakness)
    4. Do not forget to use im- before a word that starts with ‘m’ or ‘p’, e.g., immature, impatient, improbable.
    5. Similarly, ir- before a word that begins with ‘r’ and il- before a word that starts with ‘l’, for example, irreplaceable, illegal, illegible, illiterate, irreversible.

    Exceptions:

    1. Not all words starting with ‘dis’ are an antonym.
    2. Example:

      distinguish means ‘to differentiate’.

      I am unable to distinguish between the two.

    3. Not all words starting with ‘im’ are an antonym.
    4. Example:

      impart means to convey or pass on.

      It is a teacher’s job to impart knowledge to students.
