Final answer:
The suffix used to change a verb into a noun that indicates a condition is '-ness'. It is an essential part of English grammar that helps in forming nouns from verbs, which denotes a specific state or condition.
Step-by-step explanation:
The suffix that is typically used to convert a verb into a noun to indicate a condition or state is -ness. For example, when adding -ness to the verb "happy," one forms the noun "happiness," which describes the state or condition of being happy.
Another example is the verb "forgive," which becomes "forgiveness"—the noun that means the condition of having forgiven or being forgiving. Similarly, "dangerous" becomes "dangerousness," signifying the state of being dangerous.
Understanding Suffix Pronunciations
Suffixes like -ed can have different pronunciations such as [t], [d], and [id], changing the sound but not the meaning. For instance, "dried" can sound like drai-d, and "accepted" can be pronounced as accept-id. Knowing the correct pronunciation is essential in using these suffixes accurately.
