Logical connectors are used to join or connect two ideas that have a particular relationship. These relationships can be: sequential (time), reason and purpose, adversative (opposition and/or unexpected result), condition.
Within each category, the words used to join the ideas or clauses are used differently, with different grammar and punctuation.
Subordinating conjunctions
Introduce adverb clauses
Either the dependent clause or the independent clause may come first in the sentence, with no change in meaning
ex: Before he came, we didn't have a physical education teacher.
We didn't have a physical education teacher before he came.
Prepositions
Is followed by a noun or noun phrase
Either clause may appear first
ex: He didn't come to class due to his illness.
Transitions and Conjunctive adverbs
Joins two sentences separated by a period or two clauses separated by a semi-colon.
Only one possible order of the sentences
The transition may appear clause initial, clause final, or between the subject and verb of the second sentence.
ex: He was sick. Nevertheless, he came to class.
Conjunctions
One possible order
A comma is used before the conjunction
In academic writing, do not begin a sentence with a conjunction
ex: He didn't do his homework, so he didn't pass the class.
