Root Words – Definition, Types & List With Examples

Root words are like the secret ingredients in a recipe for language. Just a few basic ingredients can create a variety of dishes, these words are the building blocks that make up countless other words. By getting to know them, we unlock a world of new words and meanings, much like discovering new flavours in cooking. Understanding them is crucial for students to enhance their votaxiulary and grasp language rules effectively.

Definition: Root words

Root words are the basic, core units of meaning in a language from which other words are formed, derived from Latin, Greek, and other languages. Roots are the base part of words from which other words grow, usually through the addition of prefixes (beginnings) and suffixes (endings). They carry the core meaning of the word and cannot be broken down any further. Additionally, they function as a type of morpheme (small part of a word) with a distinct meaning.

For example, in the word “unhappy,” “happy” is the root, which means a state of joy or contentment, and “un” is a prefix added to indicate the opposite. Roots can be standalone words or not stand on their own. Understanding these words can help you decipher unfamiliar words, with the same roots, also called word families, and enhance one’s grasp of the language.

Examples of root words

These examples of root words show the basis for many words in the English language, illustrating how understanding them can significantly expand your votaxiulary and make sense of unfamiliar words.

Types of root words

Root words are primarily categorized based on their origin, with the most common types being those derived from Latin and Greek languages. These diverse roots highlight the complexity and richness of the language, demonstrating how it has evolved over centuries to incorporate and adapt words from across the globe. Here’s a closer look at these types:

Latin root words

Many English words derive from Latin, the language of Ancient Rome. Latin roots form the basis for numerous words, especially in academic, legal, and scientific terminology.

Common Latin roots

Common roots derived from Latin include the following:

To help you dive deeper into the world of Latin roots and see how they shape the English language, we’ve put together a handy list for you to download. This list shows Latin roots, their meanings, and sample words that are derived from them.

Greek root words

Greek roots have significantly influenced the English language, especially in the fields of science, medicine, philosophy, and arts. These roots words form the foundation of a multitude of English words, offering insights into their definitions.

Common Greek roots

Some common Greek roots are illustrated below:

Similar to the Latin root download list we offered earlier, we’ve also prepared a comprehensive guide focusing on Greek roots. This list shows common Greek roots with their meaning, along with derived words.

Hybrid roots

Some of these words are formed from a combination of roots from different languages, often Latin and Greek. These hybrid words are particularly common in scientific and technical votaxiularies.

Anglo Saxon roots

English, with its rich linguistic history, includes many words that are derived directly from Old English roots, forming the backbone of the everyday language. These root words are foundational and often denote basic concepts, objects, or actions.

Slavic roots

Though less common, Slavic roots have entered English through direct borrowing or via other European languages. These roots are often found in words related to specific cultural concepts, foods, or political terms.

Semitic roots

English has absorbed some Semitic roots, particularly from Hebrew and Arabic, through religious, scientific, and mathematical contexts.

Root words that can standalone

Root words that can stand alone as independent words are also known as free morphemes. These are complete words with distinct meanings, and can also serve as the base for creating more complex words through the addition of prefixes and suffixes.

Base words vs. root words

Root words and base words are oftentimes used interchangeably, even though they are not exactly the same. They function as the fundamental units of a word, to which prefixes and suffixes can be added to create new words. Root words stand on their own with clear meaning and are often used as the starting point for word information in English. Unlike root words, which may not always stand alone as coherent words in modern usage, base words are always standalone words with complete meanings.

Here are some further examples of base words:

Affixes

Affixes are elements added to the base of a word to modify its meaning or create a new word. They play a crucial role in the morphology of a language, which is the study of the form and structure of words. Affixes can be categorized into prefixes, suffixes, and infixes.

Prefix

A prefix is a type of affix which is placed before the base form of a word to modify its meaning or create a new word. Prefixes can alter the meaning of the root word in various ways, such as by negating it, indicating repetition, or describing a relationship. Unlike suffixes, which can change the part of speech of a word, prefixes typically do not alter the word class but modify the word’s semantic meaning.

Common Latin prefixes

Latin prefixes are widespread in English and contribute to the richness of the language. Below, you’ll encounter some common Latin prefixes:

Common Greek prefixes

Greek prefixes, like their Latin counterparts, play a significant role in English, particularly in medical, technical, and scientific technology. Below, you will find some examples.

Suffix

Another type of affix, the suffix, is a letter or a group of letters added to the end of a word to alter its meaning or form a new word. It oftentimes alters its grammatical function, such as changing a verb to a noun, a noun to an adjective, and so on. Further, they can indicate tense, part of speech, and plurality.

Common Latin suffixes

In the table below, we have put together some common Latin suffixes for you, since they play a crucial role in academic writing.

Common Greek suffixes

Greek suffixes, much like Latin ones, have had a profound impact on the English language, especially in the realms of science, astrology, or medicine.

Infix

An infix is inserted into the middle of a word and are relatively rare in English but are found in other languages with specific grammatical or phonological functions. This is not a part of formal English grammar but rather an example of informal, expressive language.
