ot\ or \opposite of\? * 3 points

adjective
adverb
noun
verb

what is the suffix in \scientifically\? * 1 point
-ally
-ic
-ically
-ly

Explanation:

1. The prefix "dis -" often means "not" or "opposite of". "Disappear" means to cease to be visible, which implies the opposite of appearing. "Re -" means again, "mis -" means wrongly, and "non -" is not a common prefix for "appear" in standard English.
2. "Unforgettable" describes a noun (e.g., an unforgettable experience), so it is an adjective.
3. A suffix is added to the end of a root word. In "scientifically", the root is "scientific" and the suffix is "-ally" which is used to form adverbs from adjectives.

Answer:

1. Disappear
2. Adjective
3. -ally
