a, an
a (AY)

The correct choice of the “articles” a and an depends on the initial sound of a word, not on the initial letter, of the word that they precede.

The letter a should be used before all words beginning with a consonant sound except silent h (an honor) and before words beginning with vowels that represent combined consonant and vowel sounds (university, unit).

Examples: a boy, a European, a j, a picture, a store, a table, a bottle, a window, a phone, a hyphen, and a one-horse town.

There are also words that begin with vowels that have a consonant sound. Say “unique” out loud and you will hear that it contains in its first syllable a consonant y sound as well as the vowel oo sound. You are saying (phonetically) yoo-NEEK. Similarly, “union”, “use”, and “eulogy” begin with a consonant y sound and call for the article a. If you use your ears, you will never be guilty of “an historic” or “an unique.”

Let’s repeat and expand this concept: a is used in front of words that begin with a long u (when pronounced as yoo), eu, and ew, and before the word one. Examples: a united country, a usurper, a eulogy, a ewe, a U-boat, a European, a one-horse town, and many a one.

an (AN)

The word an should be used before all vowel sounds (a, e, i, o, u). Examples: an entry, an f, an hour, an orange, an ape, an odor, an idea, an eagle, an honor, an umbrella, and an unbeliever.

One of the most common mistakes, both written and oral, is the use of an before “historical” or “historic”. When the word following the article begins with a consonant sound, the article used is a; when it begins with a vowel sound, the article used is an.

So remember, a word may in fact begin with a consonant, yet have an initial vowel sound. The word “honest” is a case in point. Say it out loud and you will see what is meant.

The initial consonant h is silent, so the word has an initial vowel sound; hence, an honest man, an hour ago, an heir to the throne, an honest and an honorable peace; on the other hand, when a word begins with an aspirated h (a speech sound followed by a puff of breath or the speech sound represented by English h), correct usage is a hotel, a house, a hill, a hymn, a honeycomb, and a history or a historical.

An advanced word: tribo- and Its Modern Applications

The “advanced words” in the following contain valuable information if for no other reason than that the concepts of tribology are so important in all of our lives. You may find some aspects difficult to comprehend, but just knowing what the Greek element tribo means, as well as some of the English words that are derived from it, will give you knowledge that is lacking even among the very educated.


This issue of Focusing on Words will present a relatively new, and not widely known, element from Greek that is used in modern engineering and physics: tribology. This Greek tribo- element means, “friction”, “rub”, “grind”, or “wear away”.

Most of the information for this subject came from an article, “Better Ways to Grease Industry’s Wheels,” from the September 28, 1998, issue of Fortune magazine written by Ivan Amato.

  • Lubrication is central to machine performance, but it’s only part of the story. More and more, the bigger picture of machine health has been going by the label “tribology” [trigh BAH loh gee] which is based on the Greek word for “rubbing.”, “grinding”, or “wearing away”, etc.
  • Tribology combines issues of lubrication, friction, and wear into a complex framework for designing, maintaining, and trouble-shooting the whole machine world.
  • Tribology is already providing data that could be used to produce transmission fluids that give automobile drivers better fuel economy and a smoother ride.
  • The most visionary tribology advocates and practitioners tend to view their field as the cure for much of what ails industry and even entire economies.
  • Tribology has evolved into a bona fide field of research and technology since 1966, when a group of industrialists in England coined the term with assistance from an editor of the Oxford English Dictionary.
  • The O. E. D. defines tribology as, “The branch of science and technology concerned with interacting surfaces in relative motion and with associated matters (as friction, wear, lubrication, and the design of bearings).” In 1968, H.P. Jost, in the February 8, 1968, issue of the New Scientist states, “After consultation with the English Dictionary Department of the Oxford University Press, we chose the term ‘tribology’.”
  • Many tribologists devote themselves to uncovering the fundamental chemical and physical dramas that underlie good and bad lubrication, friction, and wear. They are relying on new tools like friction-force microscopes, that can examine surfaces down to the molecular level (nanotribology?).
  • Transmissions are just one place where tribology makes a difference in the automotive industry. Other items on the agenda include controlling brake noise and wear, reducing internal friction in engines, and increasing the productivity, part quality, and energy efficiency of production machinery.
  • The “tribology tribe” points proudly to its crucial role in the thirty-billion dollar-a-year data-storage industry. When it comes to surfaces in motion, this is an especially harrowing arena. Yet it’s through tribological know-how that makers of hard-disk drives have been able to squeeze more and more data into less and less space.
  • The head that reads and writes information to and from a hard disk flies about 50 to 100 nanometers above the disk surface. That’s about one-thousandth the width of a human hair. Meanwhile, the disk typically spins beneath the head at about ten to twenty meters per second.
  • Woody Monroy, head of corporate communications for Seagate Technology, which makes disk drives, says that in terms of speed and clearance, it’s the equivalent of an F-16 jet fighter plane flying one-sixty second of an inch [less than one millimeter] above the ground, counting blades of grass as it goes, at Mach 813 (or 813 times the speed of sound).
  • There are many reasons computers go down, but one of the most dreaded is when the head assembly literally crashes into the spinning disk’s surface, tearing up and destroying precious data.
  • It’s a tribological triumph that, despite all the hazards, vulnerabilities, and abuse by users, most storage systems operate fine most of the time because of proper coatings. The first protective layer is at most twenty nanometers thick. One leading-edge tribo-tactic is to fiddle with the molecular structure of the thin lubrication layer on top of the disk (nanotribology?).
  • Tribologists have plenty of challenges to keep them busy, but it’s all part of making disk drives and economies run smoothly.

Boyfriends of an Elderly Woman
MY FIVE BOYFRIENDS!
1. I am seeing 5 gentlemen every day.

As soon as I wake up, Will Power helps me get out of bed.

2. Then I go to see John (the toilet).
3. Then Arthur Ritis shows up and stays the rest of the day.

He doesn't like to stay in one place very long, so he takes me from joint to joint.

4. After such a busy day, I'm really tired and glad to go to bed with Ben Gay.

What a life!

5. Now remember this: Life is like a roll of toilet paper, the closer it gets to the end, the faster it goes!
6. So have fun, think "good thoughts" only and learn to laugh at yourself and count your blessings!!!

emeralds, an emerald
Brittle gems which have a tendency to chip and are rarely flawless.

The rich green color of these stones are caused by the presence of chromium, a hard white metal.

In ancient times, powdered emerald was believed to cure fever and the plague.

Emeralds are formed from a combination of three main minerals: silicon (the chief constituent of sand and quartz), aluminum, and beryllium.

Colombia is the source of the finest emeralds.
