<img src="http://www.orchidboard.com/community/gallery/data/515/O.jpg" align=left hspace=0 vspace=0>r at least for newbies... since there's no such thing as a dumb newbie....Or was that, there's no such thing as a new dumbie?
Orchid lingo is Byzantine. Latin, actually. But just as hard to decipher as if it were from Byzantium. But it's also precise. A name can tell you A LOT about that lovely critter you're contemplating, or have just in fact purchased.
Let's start at the top. The Family is Orchidaceae. That is, orchids. This is the easy part. Now, buckle up!
The family breaks down into different genera (that's plural for genus) Kind of like opera and opus. No...not the penguin!
Each genus is a group of genetically similar plants. They can, in fact, be genetically crossed through hybridization, whether or not that happens in the wild. A group of similar genera are often referred to as an alliance. Examples might include the Oncidium alliance, the Cattleya alliance, and the Phalenopsis alliance. It's hard to say how many different alliances there are, since everyone has an opinion on how some of the weirder ones are grouped, but it's safe to say there are between 1-2 dozen.
There are hundreds of different genera, however. Lots and lots. When orchids from different genera are crossed, the resulting plant is given its own genus name. Sometimes it’s self-explanatory, like Laeliocattleya (abbr. Lc.), which is a cross between a Laelia and a Cattleya (a member for the Cattleya alliance.) And sometimes the new genus name is just plain weird, like Vuylstekeara (Vuyl.) in the Oncidium alliance, which is a cross between Cochlioda x Miltonia x Odontoglossum. Told you some were weird!
By the way, a genus or alliance name is capitalized. Although when speaking quickly on the forum we often tend to get lazy. Here's a great Website for mapping genera and their abbreviations to their parent genera: <a href="http://www.notsogreenthumb.org/orchi.../genera3.htm#P" class="bb-url">http://www.notsogreenthumb.org/orchi.../genera3.htm#P</a>
Within a genus, any number of species are found. A species is a genetically unique plant, and one that occurs in the wild. Depending on the genus, there may be hundreds of species plants. The Dendrobium genus (Den.) has over 1,600 species! Species are cool, because they’re what we find in nature. If a plant is a species, such as: Phal. equestris, the genus name (as always) is capitalized and the species name is lower cap. Lower cap means cool - learn to spot it!
Within a given species, there may be variations (typically in coloration) that are still considered part of that species. Catt. walkeriana is a great example. Note that walkeriana is a Cattleya species, because its name isn't capitalized. See how much you've learned! There is a Catt. walkeriana [with a pink to purple flower], a Catt. walkeriana var. alba [it's like an albino - all white, or white and green], a Catt. walkeriana var. semi-alba [white petals and sepals with a colored lip], and a Catt. walkeriana var. coerulea [a blue one, like it's been left too long in the cold.]
Hybrids are made by us. They don't typically occur in nature. We think one plant's color would look really cool with another’s flower form and we play Frankenstein and make it so. In this case, Frankenstein Rules allow us to name the hybrid we've just created! So long as no one has beaten us to it. So if I take a Paph. sanderianum and cross it with a Paph. rothschildianum the result becomes a Paph. Prince Edward of York. Affectionately known as a Paph. PEOY. Sorry, Sanders registered this hybrid in 1898. Go find your own creation!The hybrid name is capitalized. That tells us it's not a species. 
The term primary hybrid is meaningful as well. It tells us both parents were species. And species are really cool - don't forget!
If you see the term grex, it simply means the hybrid identity. If that nifty capitalized hybrid name hasn't yet been registered (with the American Orchid Society for us in the U.S.), the cross itself is referred to. Such as: Paph. (sanderianum x rothschildianum). That happens to be a Paph. PEOY, but you may sometimes buy or see plants that list the crossing, without mentioning there’s a name registered to the grex.
Ok, you're hanging in really well - just a couple of final points...
In any plant sex, Yeah, we always save the good stuff for the end! whether species or hybrid, the offspring will vary. Just like kids! Yet, if a particular seedling from a cross grows up and flowers with exceptional form or beauty, breeders may want to capture that Kodak moment. They can divide the plant (this is slow and makes for expensive purchases) or they can clone it. This ensures an exact remake of the genetic code and consistently lovely blooms. Unless you croak the plant through neglect or improper condidtions... 
Such genetic duplicates are known as clonal varieties or cultivars. The way to identify a clonal variety is through the name. Hey, I warned you early on there was a lot to this naming thing! If it's genetically equal to another plant it's given a clonal name. Such as: Paph. Prince Edward of York 'Sunny'. The clonal name is always capitalized and found in single quotes: 'Sunny', in this case. What's important about clonal names, is that you know pretty closely what type of growth and blooming to expect. How do you know this? I'm glad you asked, because that leads to our next point...
Several major orchid societies throughout the world award titles to plants with exceptional form and color. The American Orchid Society uses three primary awards: HCC, AM and FCC. (Increasing award value - the FCC is highest.) These are always followed by the initials of the awarding body. So a superb plant might receive an FCC/AOS. Our tag would now read: Paph. Prince Edward of York 'Sunny' FCC/AOS. And when we see that our juices flow and we have to buy it!
Well, there's free black coffee for all who made it this far. I want to mention one last thing… 
One last thing? - She's babbled far too long already - what's left?
Note name tags - particularly when purchasing! Use your shiny new knowledge to examine the tags of plants that catch your eye. 
I've chuckled at more than one box store or grocery store plant where I've seen tags like: Paph. vini coloratum. The tag would suggest a Paph. species named' 'vini', but 'vini' is simply used to describe any dark-red variety of a Paph. Likewise, 'coloratum' is just a variety descriptor for 'colorful' - with greens and purples in Paphs. So here, no species or hybrid is named, meaning they're selling you a NOID!
We use the term, NOID, to mean No Identification. That is, we have no idea what the plant is. This detracts from it's value, and also greatly reduces our mutual enjoyment. Wouldn’t you be depressed if you didn’t know your own name? Don't pay a lot for a NOID, unless you're crazy in love with it. Because having lost its past, you lose the joy of sharing it.
Congratulations! If you’re not snoring, you made it through. And armed with this knowledge, you can now show off at parties.?
