Grammar

I have been thinking about this on and off for awhile.

In elementary school I remember learning apostrophes and how to make things plural. I got the basics. When it came to the exceptions  I clicked my brain off. My last name ended with an "n" so I figured I would never have to know when the proper use of -es, -'s, and -s'.  Here I am 20 years later. A Sens. A last name ending in a sneaky "s". Even if you have a last name not ending in "s" you should know the rule. Don't make the ignorant mistake that I did. 

I combed over quite a bit of material. I learned how to spell my name.

The Definitive Guide to Pluralizing Your Last Name

Last letter(s) of last name	What should you add to make it plural?	Does it need an apostrophe?
a, b, c, d, e, f, g, h (see exceptions below), i, j, k, l, m, n, o, p, q, r, t, u, v, w, y	-s	NO
s, x, z, ch, sh	-es	NO

It’s analogous to “lenses” and “buses.” Error in writing and especially error in pronunciation are common. It seems to me that the majority of Americans say “Jones” for the plural.  Saying "Jonziz" is unnatural or uncomfortable. I say, "Sens".  It is really "Senziz". (At least that is what English grammar tells me).

Q: Is there ever a reason to add an apostrophe?
