A suffix is one or more letters or syllables added to the end of a root word. For example, when you add the suffix “-ly” to “quiet,” you get “quietly.” Common suffixes include “-ed,” “-ion,” “-ful,” and “-ment.” Suffixes can change a word’s part of speech (e.g., “freedom”), plurality (e.g., “roses”), verb tense (e.g., “worked” or “working”), and more.
Learning about suffixes is extremely helpful for improving vocabulary, spelling, and grammar. The examples and explanations below show how to spell and use a variety of common suffixes. If you want to learn even more about suffixes, follow the links at the end for more suffix examples and a suffixes worksheet.

A prefix is a letter or group of letters at the beginning of a root word (e.g., the “micro-” prefix in “micronutrient”). There are over 30 prefixes in the English language. Each prefix changes the meaning of a root word in a specific way. For example, if you add the “in-” prefix (meaning “not”) to “edible,” you get “inedible,” which means “not edible.”
Learning about English prefixes helps with reading comprehension and vocabulary. The prefix definitions and examples below show how a variety of prefixes affect the meaning of root words.

Direct speech and indirect speech/reported speech are the two ways to tell someone what another person said. Direct speech repeats the same words in the same order in quotation marks. Indirect speech/reported speech involves paraphrasing with slightly different words, so it doesn’t have quotation marks.
Reported speech and direct speech are useful in many situations, such as taking messages or telling someone about a meeting or conversation. If you’re taking an English proficiency test, you’ll probably use reported speech during the speaking or writing sections.
Direct and indirect speech both have specific grammar and punctuation rules. The following tips and examples show how to use them correctly. And when you’re writing with direct or indirect/reported speech, QuillBot’s free Grammar Checker can help you avoid errors.

Closed (e.g., “sunglasses” and “wildflower”)

NoteMany of the newest words in major dictionaries are compound words (e.g., “street corn,” “jam band,” and “freestyle”). As language evolves, dictionaries add new words at least once a year. For example, when words like “gift card” became more common, they became official words in dictionaries.

One of the most important aspects of effective writing is using different types of sentences. Sentence variety keeps readers engaged and helps you communicate your ideas precisely.
In English writing, eight types of sentences are possible. There are four types of sentences by structure (simple, compound, complex, and compound-complex) and four types of sentences by function (declarative, interrogative, imperative, and exclamatory).
Whether you’re working on essays, cover letters, or personal correspondence, the tips and examples below will help you use all eight of these sentence types effectively and correctly. No matter what types of sentences you’re using, QuillBot’s free Grammar Checker can help you avoid errors.
NoteEach sentence has one of the four possible structures and one of the four possible functions. For example, a simple sentence can be declarative, interrogative, imperative, or exclamatory. An imperative sentence can be simple, compound, complex, and compound-complex.
