IS NOT 'S! IT’S S, ALL BY ITSELF!
Do you comprehend it?
No, don’t answer yet. Take minute. Go find a dictionary. Look up alphabet. Look at the pretty chart. Notice the nifty columns. Place your finger on the one with the heading English. Run your finger down to the nineteenth letter in that column. Before you do any of this, though, you must grab your ears and pull firmly downwards. Then, and only then (when your head is free of your colon), should you search for that dictionary–I really don’t want you to bump into any walls.
Were you asleep when the teacher attempted to explain to you that the Third Person Singular form of the verb to say is says and not say’s?
Did that nap also extend to the next lesson concerning the formation of plurals?
Perhaps you had entered a coma by the time the teacher began explaining the difference between the contraction it’s and the possessive its.
Maybe you could tell me the name and address of the teacher who actually did teach you the 19th letter of the English alphabet is 's so I can discuss her knowledge, or lack thereof, of spelling.
Or perhap’s you would be more than thrilled to 'see this 'site renamed The 'Straight Dope, by Cecil Adam’s. Maybe you think the name of the country in which I re’side i’s the United 'State’s of America. Perhap’s you 'spend the morning reading the new’spaper’s, but only the comic’s 'section’s, of cour’se.[sup]*[/sup]
Do you see how jarring that is?
Lay off the poor apostrophe (see quote below)!
p.s. Yes, I realize I have made the mistake once or twice of pluralizing a noun with 's, and even of switching its and it’s once or twice. What I’m complaining about here is the constant erroneous usage.
