Conjunctive adverbs connect one clause to another clause, or one idea to another idea:
Joanne was very good at math; however, she is not good at English.
Descriptive adjectives can be separated with commas in a sentence such as:
Joanne did not want to pet the smelly, wet dog.
She knows she is not bright. Like good looks and money.
