My daughter was reading a book and asked, “Mom, what does the word er mean? This character says it all the time.”
I replied, “Well, it’s not really a word, but it’s used as a pause in conversation. Like, uh.”
“Oh. So should I replace all the er’s with uh’s?”
“No, they mean the same thing.”
“But, you said that er isn’t a word?”
“Neither is uh.”
Nothing like trying to explain the idiosyncrasies of the English language to your daughter, only to have her look at you like you’re speaking Greek.
