Hi, I have problem with my homework..
Please help me

Consider the following group of examples. Characterize the formal pattern via which these examples are formed (your characterization should state the gramatical class of the base, the shape of affix and the grammatical class of derived word) Offer a semantic paraphrase applicable to the entire group under consideration.

loyalty, cruelty certainty novelty safety

Thanks for your help,
