This guide covers 249 conjunctions, listed in alphabetical order. The selection includes common everyday words, paired forms, and less familiar connectors found in speech and writing.

Conjunctions are words that join words, phrases, or clauses into a single sentence. They show how ideas relate, such as addition, contrast, cause, condition, or time. Grammarians group them into coordinating, subordinating, and correlative types, and some adverbs also work as connectors. Without them, writing would break into short, choppy statements, so they matter in everything from casual chats to legal documents.

Interesting and little-known facts about Conjunctions:

• The word “conjunction” comes from the Latin “coniunctio,” which means “a joining together.”
• English has only seven coordinating conjunctions, and teachers remember them with the acronym FANBOYS: for, and, nor, but, or, yet, so.
• “And” is one of the most frequently used words in English, often ranking in the top three.
• Correlative conjunctions always work in pairs, such as “either…or,” “neither…nor,” and “not only…but also.”
• The rule against starting a sentence with “and” or “but” is a myth, and respected writers have broken it for centuries.
• The 1973 educational cartoon “Conjunction Junction” taught a generation of American children how these words work.
