What is the prefix in irregular. What does it mean?

To determine the meaning of the underlined word "irregular," we can break it down using the knowledge of prefixes and suffixes.

The prefix "ir-" means "not" or "opposite of." In this case, "ir-" indicates that something is not regular or not following a set pattern.

The base word "regular" means something that is consistent, steady, or follows a specific pattern.

The suffix "-ar" in "irregular" is used to form adjectives and means "of or pertaining to."

Therefore, based on the meaning of the prefix "ir-" and the base word "regular," we can determine that the word "irregular" means "not following a set pattern."

So, in the sentence, the fire alarm bell rang at "irregular" intervals means that it did not follow a consistent or predictable pattern.

The correct answer is d. following no set pattern.
