In this case it is not a grammatical question. This are two words that mean exactly the same, with the difference that dynamic also can be used as a noun and dynamic beeing more common.(edited contradiction rofl)

The word dynamical is used to be known only in a educated/scientific audience, so if you like to sound intellectual, not like the usual tler, you should use it. A poll would direct you to dynamic tho.

In fact you're right.
The language is made up by the speakers of that language. If all of a sudden everyone says dynamical it would become a new word.

Only ever heard the world dynamical in "Dynamical Systems".

As i already pointed out, you are wrong in this case because the main difference between these two words is that "dynamic" is more common.

I was joking. In physics there is a particular branch called "dynamics" so the implied noun form is dynamic for particular results and the adjective is "dynamical." i
It is nothing more than an attempt at disambiguation.

I've never head the word dynamical. I don't think many people ever have. Best to stick with dynamic imo. Personally, if I heard someone say dynamical (if I hadn't seen this thread) I'd be skeptical.

I've changed many instances of "dynamical" to "dynamic" in LP...because "dynamical" is redundant, dumb, and redundant. My personal belief is that "dynamical" got started the same way as "irregardless" but nobody noticed fast enough, so it became "real" (but it's still dumb).

There are a few legitimate uses of the word though, such as a Dynamical System.

Dynamical would essentially mean exactly the same thing but sounds completely retarded. Similar examples are: Economical and Majestical.

Americans seem more likely to add the "-al" and they're never right about the language. Seriously, it sounds stupid.

I'm an American who's read quite an extensive set of American literature and published material, and I've never heard of the term Dynamical, Majestical or Economical (except in the sense of being efficient).

There's a branch of mathematics called "dynamical systems", but never "dynamic(s) systems".

Possibly the word has the merit of being part of another, actually useful word: "dynamically."

just like ironical can be used in lieu of ironic, dynamical can be for ironic. But it makes you look like a douchey know it all (ie really fucking good hehehe).

Pretty much any adjective you can think of that ends in "-ic" has the alternate ending "-ical". Sometimes the "-ic" version is more common (as with this word), sometimes the "-ical" version is more common (ex. "cylindrical"). I can't offer a good reason for this redundancy except that English is a rather haphazard language. Sometimes the two versions evolve to develop different connotations (like the scientific use of "dynamical" that people mentioned) but often they remain virtually identical except that one becomes dominant.

Hm, luckily only two pages, so there's still hope.

Try to form the adverb to "dynamic" without -al(l).
Now try the same with -al(l).

Now let's assume there's someone who reads "...is dynamically adjusted..." and wants to change the adverb to an adjective. Have a guess what the result will be.

By the way, there's a discussions page on leo.org. Use it.

typical = typic
theoretical = theoretic
identical = identic
heretic = heretical
grammatical, no "grammatic"

good to know your tongue... Oh, only because a word seems not so super cool doesn't make it wrong.
Also beeing "redundant, dumb, and redundant" in your opinion, does not make it wrong either, nor you may never heard of them except in one sense does make it wrong, nor you look very smart.

@dagobert: read the opening post, he already read leo.org s discussion :p

I think dynamical might have a special meaning in math, cuz my dad wrote a book on something like that...

"Qualitative Theory of Dynamical Systems"

My English teacher used to use "ironical" all the time when I would have used "ironic." I never really understood the difference, if there even was one, but I just trusted that he used it correctly. I am fairly certain he knew what he was talking about.

Edit: I think "-ic" is just another of the suffixes, so my previous thought here, is probably wrong...

Could that be the answer? I didn't really pay attention to it at the beginning, but if I compare with German, we have the suffix "-isch", or "-lich" to make an adjective out of a noun. As I understand it, it's the same with "-al" in English. (Klinik - klinisch; Historie - historisch; clinic - clinical; history - historical)
There are also suffixes to make a noun out of an adjective (happy - happiness;...). In some way the original form is either an adjective or a noun, and the other part can be constructed. For "dynamic" the adjective is the original form, so "dynamical" sounds like "happical", or something like that.
But then there is the specific field in physics, chemistry and, as you say mathematics called "dynamics". Although it's called so, because it describes dynamic systems, it's seen as a new noun and thus the fitting adjective would be dynamical.

(Maybe I'm totally wrong, but thinking about this surprisingly is kind of interesting.
