Sense words can either express experiencing the sensation or expressing an action being taken to acquire a sensation. In English, these are:
| Active | Passive | |
| look | see | |
| listen | hear | |
| touch | feel | |
| sniff | smell | |
| taste | taste | |
In Lojban, there are few dedicated gismu:
| Active | Passive | |
| sight | catlu | viska |
| sound | tirna | |
| touch | pencu | |
| scent | sumne | |
| taste | ||
| generic | zgana | ganse |
There are two options of lujvo. Naming based on the sensory organ gives:
| Active | Passive | |
| sight | kalzga | kalga'e |
| sound | kerzga | kerga'e |
| touch | pilzga | pilga'e |
| scent | zbizga | zbiga'e |
| taste | tacyzga | tacyga'e |
Naming based on the thing being sensed gives:
| Active | Passive | |
| sight | vinzga | vinga'e |
| sound | snazga | snaga'e |
| touch | te'uzga | te'urga'e |
| scent | panzga | panga'e |
| taste | vu'izga | vu'irga'e |
is to replace the current set of sensory predicates with another one.
The scheme is still not complete. Let's put all sensory aspects into one table.
These are the predicate that we might get (I will give them temporary names in curly brackets).
{HEAR} - x1 hears object(e.g. musician)/event (e.g. concert) x2, listens to it and defines x2 as x3 (noisy, loud, sweet, lovely, romantic etc.)
{SEE} - x1 sees object/event x2, looks at x2 and defines it as x3 (green, that it looks ugly etc.)
{SMELL} - x1 smells object/event x2, observes x2 and defines it as x3 (e.g. flowery,pungent, musk)
{TASTE} - x1 tastes object/event x2, observes x2 and defines it as x3 (e.g. tasty, sweet,sour)
{TOUCH} - x1 touches x2, observes (tries) x2 and defines it as having texture x3 (e.g. rought)
As you can see we actually need valsi with three places. "observe" is a variation of each predicate that can be best expressed using additional {jundi} or {zgana}.
This scheme is consistent. The only problem is that it doesn't correspond to the current mess of sensory gismu.
The only gismu that corresponds to this scheme is {te panci}.
Probably {te jvinu} as well (thanks xorxes for pointing out!) and {te skari}.
tirna3=viska3=skari4 is something that we can also place in every sensory gismu.
However, they can be easily expressed using {va'o}.
gua\spi's {vyi=X1 sees object X2 against background X3} looks like lojbanic tirna3.
{sumne} is a superfluous gismu.
{vrusi} overlaps the senses of taste and smell (against the policy of lojban one word=one meaning).
In gua\spi there are a bit better definitions, e.g. {xel=X1 smells like prototype (xi) X2*}.
This is something that definitely needs revision.
We have five senses and we must clearly express what we feel.
