Finding the Correctly Spelt Word

The question asks us to identify the word that is spelt correctly among the four given options. Let's examine each option carefully to find the correct spelling.

Here are the options provided:

1. imunize
2. immunaize
3. imunaize
4. immunize

We need to determine which one follows the standard English spelling rules for the word related to making someone immune.

Let's analyze each option:

• Option 1: imunize. This spelling is missing one 'm'. The standard spelling requires two 'm's.
• Option 2: immunaize. This spelling has two 'm's correctly, but it uses 'aize' at the end instead of 'ize'. The correct ending is 'ize' or 'ise' (depending on regional variations, but 'ize' is common, especially in American English).
• Option 3: imunaize. This spelling is incorrect on two counts: it's missing an 'm' and it uses 'aize' at the end instead of 'ize'.
• Option 4: immunize. This spelling includes two 'm's and ends with 'ize'. This matches the standard spelling of the word.

Based on the analysis, the correctly spelt word is "immunize".

Additional Information on the Word Immunize

The word "immunize" means to make a person or animal immune to infection, typically by vaccination. It is derived from the word "immune". The spelling "immunise" is also considered correct, particularly in British English. However, among the given options, "immunize" is presented as the correct form.

Understanding common prefixes and suffixes can help with spelling. The prefix 'im-' or 'in-' often relates to negation or 'into'. The root word here is related to 'immune'. The suffix '-ize' or '-ise' is used to form verbs meaning to make or become like. In this case, 'to make immune'.
