Here's why:
* Coordinating conjunctions connect words, phrases, or clauses of equal grammatical rank. Common examples include "and," "but," "or," "nor," "for," "so," and "yet."
* Conjunctive adverbs are words or phrases that connect clauses and show the relationship between them. They often act as transitions between ideas, like "however," "therefore," "moreover," "furthermore," "nevertheless," and "consequently."
How "however" works:
"However" indicates a contrast or exception to what was stated previously. It acts as a transitional word, connecting two clauses that often present opposing ideas.
Example:
* "The weather was terrible, however, we still enjoyed the picnic."
Here, "however" shows the contrast between the bad weather and the enjoyment of the picnic.
While "however" has the grammatical function of a coordinating conjunction, it is categorized as a conjunctive adverb due to its specific role in connecting and transitioning between clauses.
