Would devistated be a suffix?
Devastated itself is not a suffix. The -ed in devastated is a suffix however.
You can't ask for a "suffix" in a sentence. That's impossible. A suffix is the ending part of a word, like "abnormally." "Ab" would be the prefix, "normal" would be the base or root word, and "ly" would be the suffix. Perhaps you mean what is the predicate of the sentence. In that case, the complete predicate would be, "made people's jobs much easier," and the simple predicate would be, "made."
