1. In grammar:
* Conjunctions are words that connect words, phrases, or clauses. They act like glue, holding different parts of a sentence together.
* Examples: and, but, or, so, yet, because, although, since, while, if, unless, etc.
* How they work:
* Coordinating Conjunctions: Connect words or phrases of equal grammatical rank. (e.g., "The cat and the dog played together.")
* Subordinating Conjunctions: Connect a dependent clause to an independent clause. (e.g., "We went to the park because it was sunny.")
2. In astronomy:
* Conjunction refers to the alignment of two or more celestial bodies in the sky from the perspective of an observer on Earth.
* Examples:
* A conjunction of the Sun and Moon causes a solar eclipse.
* A conjunction of planets is when two or more planets appear close together in the sky.
3. In mathematics:
* Conjunction is a logical operator that combines two statements into a single statement that is true only if both of the original statements are true.
* Symbol: ∧ (logical "and")
* Example: "The sun is shining and the birds are singing." This statement is true only if both the sun is shining AND the birds are singing.
To understand the meaning of "conjunction," it's important to consider the context.
