sorry i posted earlier that a conjunctive adverb joins independant clause and dependant clause. I now know thats incorrect. A conjunctive adverb joins two independant clauses.
so hopefully the sentence below is closer to being correct.
hopefully two independant clauses joined by a conjuctive adverb.
I had previosly submitted a design to be printed at a local tshirt
company; subsequently ,the manager and general public showed a keen interest.
thank you please hope somecan help.
