Prefixes to Study for the Miller Analogies Test (MAT)
The Miller Analogies Test (MAT) is all about word analogies. Understanding a word’s definition is often critical to success on the MAT, so memorizing common prefixes can help tremendously.
Knowing your roots, prefixes, and suffixes isn’t a cure-all because the English language likes to break its own rules now and then, but it can help you through some tough questions when you just can’t recall the word’s dictionary definition. Here you’ll focus on learning common prefixes.
A prefix is letters attached to the front of a word that alter its definition. Some prefixes are so common and well known that they’ve actually become words in their own right. For example, the prefix ultra-, which means beyond, can be used as an adjective (she’s ultra-cool).The word prefix itself has a prefix, pre–, which means comes before.
An example of a prefix in action is found in the word anti-inflammatory. The prefix anti– often means against, and the word anti-inflammatory means against inflammation.
Just like word roots, prefixes don’t always make a word mean what their definitions below indicate, but they’re better than nothing when you don’t know the meaning of a word.
