Semi-What?

My lovely wife and I were driving across the country, and happened to pass a semi. You know what a semi is. I know what a semi is. But what occurred to us at 3 in the morning is that semi is actually a prefix.

So the question became semi-what? I've driven a truck (when I was in college), but somehow the fact that you could read was considered enough for your class A license. The finer points of linguistics just didn't come up.

Any ideas?

Semi is short for Semi Detached. I asked a cop, he couldn't tell me what a fully detached trailer was. That is, besides one sitting alone in a parking lot.

I think it is as opposed to a fully attached truck. Kind of like a U-Haul truck where the box is attached to the cab. I guess semi-detached sounds better than semi-attached. Kind of a glass half-empty half-full idea.

Oh my life is complete! Every time I take a road trip I wonder this exact question, but have never actually remembered to ask. I feel like the smartest person in the world. haha. Of course, I shouldn't, seeing as how I didn't figure it out. But just knowing something that I've wondered for so long is wonderful. Oh happy day!

I hate to disagree with the police, but my Driver's Educatino book says differently. According to the book, it's short for Semi tractor-trailer. Which I assume is half a truck (just a cab), and a trailer (what they're hauling). Although the other definition makes sense, too.

Why does this conflict with MW online (not to mention your mailbag answer)?

A semi tralier is indeed different from a "regular" trailer. A semi trailer only has wheels at the back end, and rests its front on the tractor. A "regular" trailer (or a full trailer, I guess) has wheels at the front and the back, and only has a tounge that attaches to a tractor. Think of a farm trailer, the kind that carries hay around here....wheels at all corners.

Must a semi trailer be, philosophically, ipso facto semi not be?

guess) has wheels at the front and the back, and only has a tounge that attaches to
a tractor.

On the other hand, the things you tow a forklift or whatever on only have a single set of wheels and a tongue and they're just called trailers. Go figure. I'm referring to the trailers we use at work (landscaping company) to haul things around on. I certainly wouldn't call it a semi-trailer.

Well, when I was a pup, the public, at least, actually mostly only called -- pretty much the whole rig -- a 'semi-trailer'. Only later did the public start calling them 'semis', 'tractor-trailers', 'rigs', '18-wheelers', etc.

You should all believe Jeff, he always speaks true.

Also, you should check the Archives (altho, I have to say, the search engine didn't turn this up when I searched for "semi" for "trailer" nor for "truck", so I'm really not being critical with ya for not finding it in the Archives.)

That is one of the dumbest things I have read on this board.
I'm not trying to start a flame war here, but that really irks me.
Most of the drivers I know are very well qualified, none of them are 'semi-intelligent' as you put it, and I know several drivers that have college degrees.
What I would like to know is where do people get information like that. The drivers that I know and work with daily do everything they can to be professional at all times and do nothing to give those impressions at all.

[Omniscient]

Jokes, god damn it, just jokes. Take a valium.

[kellibelli]

You are all wrong!
Semi refers to the driver!

Semi-educated
semi-intelligent
semi-qualified
etc.
At least that's what it means in canada...

[kellibelli]

well, that proves the semi-intelligent assertion.


Its just a joke for pete's sake!

My own father was a trucker for years, my Dad, and my brother are still involved in the industry, my ex, (shitboy) drives truck, as does his father and uncle.....(trust me, the above description fits shitboy pretty well)


My making a generalization like that is no different than Coldfire's thread about women drivers...do I think all truckers are morons...of course not!

But some are.

I don't doubt that what you say is true. On the other hand, the most dangerous and potentially life-threatening situatons I've been in on the road almost all involved semi truck drivers. On separate occasions, two friends of mine were run off the road by semi truck drivers.

I'm sure all of us have had the experience of a semi truck driver tailgating us on the highway. It's incredibly dangerous. I witnessed an accident in which a semi truck driver rear-ended a slower-moving car in the right lane of an interstate highway, even though there was plenty of room to pass. The car literally became airborn. It's amazing nobody was killed.

I'm willing to accept that most truck drivers behave responsibly, but there will always be some who do not. When I almost get squashed into the pavement or smeared against an embankment, it's definitely the bad truck drivers that make the lasting impression.
