A conjunction is any conjoining, connecting artifact, or can be the union formed by a joining or combining.
Astronomy - any apparent close approach of objects in the sky
Logic - A conjunction is a compound proposition that is true if-and-only-if all of its component propositions are true. It can also be the relationship among the components of such a proposition, usually expressed by AND or &/or.
Part of Speech - A conjunction is a word that links words, phrases, or clauses together. You would use it when you were writing a story or report. To remember all of the coordinating conjunctions, just remember FANBOYS [for, and, nor, but, or, yet, so]
Conjunctions can be any member of a small class of words distinguished in many languages by their function as connectors between words, phrases, clauses, or sentences (e.g. as, and, because, but, however) or can be any other word or expression that performs a similar function.
Conjunctions are traditionally categorized into several types: coordinating conjunctions, subordinating conjunctions and correlative conjunctions. Some examples of each follow.
* Co-ordinating conjunctions: and, or, nor, for, but, yet, so
* Subordinating conjunctions:because, since, while, before, after, unless
* Correlative conjunctions: if...then / either...or / neither...nor / both...and / whether...or /not only...but...also/ as...as
The coordinating conjunctions can be used to link sentences together where neither is subordinate to the other. Subordinating conjunctions introduce subordinate clauses. Correlative conjunctions come in pairs that must appear together in the same sentence.
Some conjunctions can also link phrases that are smaller than whole sentences. For example, the coordinating conjunctions and and or can be used to link almost any phrases so long as they are of the same type:
- nouns: I like [cats] and/or [dogs].
- noun phrases: I like [this cat] and/or [that dog]
- verbs: The cat [scratched] and/or [bit] the dog.
- verb phrases: The cat [scratched the dog] and/or [bit the mouse].
- prepositions: The cat climbed [up] and/or [down] the tree.
- preposition phrases: The cat climbed [up the tree] and/or [down the wall].
- adjectives: I like very [energetic] and/or [playful] cats.
- adjective phrases: I like [very energetic] and/or [extremely playful] cats.
- adverbs: It climbed very [energetically] and/or [playfully].
- adverb phrases: It climbed [very energetically] and/or [extremely playfully].
- sentences: [The cat climbed up the tree] and/or [the dog barked].
A conjunction connects words, phrases and clauses. The 3 types of conjunctions are coordinating, subordinating, and correlative. Coordinating are for, and, nor, but, or, yet, and so. Subordinating conjunctions include as, since, if, although, and because. And correlative conjunctions come in pairs: either/or, neither/nor..
