The comma offers a pause, a break, in a sentence. The comma is a much needed in punctuation, and in life. The comma comes as a grateful welcome when I read German with its extraordinarily long compound words that make some paragraphs a page long. Punctuation has entered newsworthy status as I have heard about a long-distance truck drivers union winning a legal battle regarding overtime because of the Oxford Comma placed in the wording of a contract. Similarly, an entertaining BBC short video about a person who blurs the lines of ethical vandalism as he lurks around high streets changing grammar mistakes in shop signs and advertising. The person tapes over misplaced apostrophes in the dark of night.
The comma can change meanings of sentences. I’ve discovered the change of of meaning in the simple phrase, “Ja, ja”. “Yes, yes” as a statement of agreement, and then if the pause on the comma is too long, and the tone perceived as sarcastic, “Ja, ja” comes across in a vastly different way that is taken as an insulting slight, like “whatever”, or much worse.
On my day off, like a comma in a sentence, I went on a gentle bike ride. The ground is only slightly graded so that there are no real hills to encounter, and only occasionally would I need to pedal. Mounded fields are beginning to yield asparagus. Poly-tunnels shelter acres of strawberries. Storks are nested upon tall posts. Before I knew it I found myself at the Rhein. While not a long journey, only a 26 Kilometres round-trip, it was a welcome pause that changed the sentence of my day.
