A conjunction is a part of speech that connects words, phrases, or clauses, coordinating or subordinating them within a sentence. In English, common coordinating conjunctions include "and," "but," and "or," while subordinating conjunctions include "because," "although," and "while." The Hebrew translation for "conjunction" is חיבור (ḥibur). In Spanish, it is conjunción, in French conjonction, and in German Konjunktion. Conjunctions play a crucial role in sentence structure, enabling the creation of complex and compound sentences by linking ideas and establishing relationships between them. They can indicate addition, contrast, cause and effect, or other logical connections, thereby enhancing the clarity and coherence of written and spoken language.
