Occasionally I come across an adult who still thinks it’s improper to start a sentence with a conjunction. Others think that starting a sentence with a conjunction is an innovation and should be done only sparingly, if at all. For those folks, I offer this passage from the King James Bible (circa 1611). I’ll put the passage in blue and the first word of each sentence in red.
And so it was, that, while they were there, the days were accomplished that she should be delivered. And she brought forth her firstborn son and wrapped him in swaddling clothes and laid him in a manger; because there was no room for them in the inn. And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord. And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger. And suddenly there was with the angel a multitude of the heavenly host praising God and saying, Glory to God in the highest, and on earth peace, good will toward men.
By my count, there are nine sentences; eight of them begin with a conjunction.
