b) invisible: visible
a) really: real
The elements we add to a word in order to create new meaning and new vocabulary are called prefixes and suffixes. If we add something to the beginning of the base word, we call it a prefix. Prefixes usually change the meaning of the word, but not the class. If we add something to the end of the base word, we call it a suffix. Suffixes usually change the word. In pairs, take a look at some other words and discuss their possible meaning. Then, classify them in the chart and underline their prefixes and suffixes.
