latro'a a= nd I devised a system for making arbitrary units in Lojban. Our system invo= lves making a zi'evla for every unit you want, and defining it using a = special kind of tanru. Working under the assumption that XI+PA forms #FREE,= we created two experimental cmavo: {pi'ai} (KE) and {te'ai} (XI).<= /div>

{pi'ai} is used as a prefix to indicate that the un= it-selbri are being multiplied to form a new unit selbri. {te'ai} is us= ed after a unit selbri to exponentiate it.
We can easily create t= he units for velocity, m*s^-1, with this system as follows:=A0

1) prefix the tanru with pi'ai; {pi'ai ...}*
2) dete= rmine the unit selbri that we need: {mitre} and {snidu}; {pi'ai mitre s= nidu}*
3) exponentiate accordingly; {pi'ai mitre snidu te'= ;ai ni'u pa}

Because this new unit tanru is long, we need to make up= a brivla for it based on its components ideally. To indicate that it was c= reated with this method, we decided that prefixing it with pi'air- migh= t be a good idea, but perhaps that the prefix can be dropped contextually.<= /div>

{pi'airtredilsnidu =3D x1 measures x2 metres per se= cond (by standard x3)}
=3D pi'ai mitre snidu te'ai ni'= ;u pa

Some of you may hate this system, and that&#= 39;s okay. It's not like I approve of everything everyone does either.<= /div>

I hate this system just becaus= e you have to create new zi'evla every time you use a new formula (yes,= just like in natlangs!).
But speed is just "Length/time&quo= t;. Just a simple formula.

i.e. i wish someone could express Length/time, not spee= d in a concise way.

That comment makes me think that you didn't quite= read the whole e-mail... Excuse me if you did.

I did introduce two experimental cmavo that allow us to multiply toget= her unit selbri. (As for your Latin citation... I'm sorry, but multipli= cation is where baby units come from.)
The unit selbri for "= length/time", with this system, is {pi'ai mitre snidu te'ai ni= 'u pa}. I am willing to bet that it is as concise as it's going to = get for what it does, which is a lot.

This system is wonderful because it doesn't *require* the creation= of lujvo *or* zi'evla. You would only do that if the unit is actually = useful for every day purposes. (If it's only useful for one author in o= ne super-technical paper, he or she can say {<complicated unit> cei &= lt;some temporary zi'evla>} and all is well.)

Also, as for "having to create new zi'evla every time you use= a new formula, just like in natlangs", I think you're misundersta= nding something about Lojban: knowing the gimste and the grammar like that = back of your hand is not enough. Lojban vocabulary is extremely lacking in = technical fields. Even only slightly technical fields. A word for &q= uot;speed" wouldn't be a bad thing, you know. And neither would a = word for every useful unit.
