Pick out the word from the following options without a prefix :

Question

Accepted Answer

Explanation:

1. **Option 2: Energy**  
   - The word "Energy" does not have a prefix. A prefix is a group of letters added to the beginning of a word to change its meaning. In "Energy," there is no such addition; the word stands alone without any prefix. It is a base word that refers to the capacity for doing work or the power derived from physical or chemical resources.

2. **Option 1: Encourage**  
   - The word "Encourage" contains the prefix "en-." The prefix "en-" is used to form verbs that mean to cause a person or thing to be in a particular state or to engage in a particular activity. In this case, "en-" is added to "courage" to mean to give support, confidence, or hope to someone.

3. **Option 3: Ericlose**  
   - The word "Ericlose" appears to be a typographical error or a non-standard word. However, if we consider it as a variation of "enclose," it contains the prefix "en-," which means to surround or close in. Therefore, it has a prefix.

4. **Option 4: Endanger**  
   - The word "Endanger" contains the prefix "en-." The prefix "en-" is used here to mean to put in danger or to expose to harm. Thus, "endanger" is formed by adding the prefix "en-" to the base word "danger."

In conclusion, Option 2, "Energy," is the correct answer because it is the only word among the options that does not have a prefix. The other options all contain the prefix "en-," which alters the meaning of their respective base words.
