In which of the following word: "en' is not used as a prefix:

The correct answer is '2' i.e. envy .

Key Points

• Prefix “en-” typically means "to cause to be" or "to put into or onto", and is used to form verbs from nouns or adjectives.
• Option 1: enlist – The prefix "en-" is used with "list" to mean "to enroll or sign up", especially in military service.
• Option 3: encourage – "en-" is used with "courage" to mean "to give courage". This is a typical use of the en- prefix.
• Option 4: enlighten – "en-" is used with "lighten" to mean "to give light or understanding". This again uses "en-" as a prefix.
• Option 2: envy – This word does not contain the prefix "en-". It is a standalone root word derived from the Latin *invidia* (meaning ill will or jealousy), and not formed by adding a prefix to a base word.

Correct sentence: “Envy” is not a word formed with the prefix “en-”; it is a root word by itself.

Additional Information

• Common words with “en-” prefix: enable, enlarge, empower, enrich, endanger – all use “en-” to express causation or transformation.
