Question

How does adding OUS to change?In fact to infectious change the words part of speech

Answer 1

The addition of "OUS" to the word "infect" changes the word from a verb (infect) to an adjective (infectious).

• Infect (verb): To affect with a disease or to contaminate.
• Infectious (adjective): Capable of being transmitted; likely to spread to others.

So, when "infectious" describes a laugh, it suggests that the laugh not only affects one person but can spread to others in a joyful way, creating a positive atmosphere.
