## Toward a quantitative form of Lojban

math terminology proposes some technical terms, but it's light on words that are useful in everyday life. I think there are plenty; I'm starting this list. mi'e jezrax (I think xod added most of this.)

• selcmi, klesi (sets)
• superset - selkle
• set, subset - klesi
• proper subset - nalrolmeilei (from the jvoste)
• cmima x1 is a member of set x2 [x1 may be a complete or incomplete list of members; x2 is normally marked by la'i/le'i/lo'i, defining the set in terms of its common property(ies), though it may be a complete enumeration of the membership];
• gripau x1 is a subset of set x2 [girzu pagbu, set-part]
• disjoint -
• overlapping (with non-empty intersection) -

Note: klesi is a set defined by a rule; selcmi is a set defined by its membership.

• fancu (functions)
• monotonically increasing - farstodi zenba
• monotonically decreasing - farstodi jdika
• bounded above - galseljimte
• bounded below - dziseljimte

• cuncmaci (statistics)
• statistically independent -
• correlated -
• fadytercu'o x1 = cunso3 (set) follows a Gaussian probability distribution with independent variable x2 = cunso

• Simple relationships (zbepi terki'i)
• du x1 is identical to x2, x3, x4, ...
• dunli x1 is equal/congruent to x2 in/on property/quality/dimension/quantity x3 [same in quantity/quality (not necessarily in identity); 'analogy' may be expressed as the equivalence of two properties of similarity (ka x1 simsa x2) and (ka x3 simsa x4)] (.ua zo du cu dunli jenai du zo dunli .i le si'o du kei cu du le si'o dunli fi ko le ka bu'a)
• mleca x1 is less than x2 in property/quantity x3 (ka/ni) by amount x4 [also negative (= nonme'a)];
• jdika x1 (experiencer) decreases/contracts/is reduced/diminished in property/quantity x2 by amount x3
• zmadu x1 is greater than x2 [also positive (= nonmau)];
• zenba x1 (experiencer) increases/is incremented/augmented in property/quantity x2 by amount x3
• dubjavme'a x1 is less than or equal to x2 [du ja mleca, equal or less]
• or nalmau x1 is not greater than x2
• dubjavmau x1 is greater than or equal to x2 [du ja zmadu, equal or greater]
• or nalme'a x1 is not less than x2
• tamdu'i x1 is similar to x2 [tarmi dunli, shape-equal]
• turdu'i x1 is isomorphic to x2 [stura dunli, structure-equal]
• pabdu'i x1 is proportional to x2 [parbi dunli, ratio-equal]
• na'ujbi x1 is approximately equal to [namcu jibni, number-near]
• lamji x1 is adjacent/beside/next to/in contact with x2 in property/sequence x3 in direction x4 [also touching, contiguous, against];

• Assorted useful brivla (vrici selpli brivla)

• fancu x1 is a function/single-valued mapping from domain x2 to range x3 defined by expression/rule x4 (ru'a le fancu cu cmene le velfancu)
• manri x1 is a frame of reference/standard for observing/measuring/determining x2, with/by rules x3
• ckilu x1 (si'o) is a scale of units for measuring/observing/determining x2 (state)
• cimde x1 (property - ka) is a dimension of space/object x2 according to rules/model x3
• morna x1 is/reflects/represents a pattern of forms/events x2 arranged according to structure x3 [x3 is a [[model] for x1 (= termontai, or the more abstract = termonsi'o);
• mokca x1 is a point/instant/moment [0-dimensional shape/form] in/on/at time/place x2
• linji x1 is a line/among lines [1-dimensional shape/form] defined by set of points x2. [ray/vector (farli'i or porli'i)]
• plita x1 is a plane [2-dimensional shape/form] defined by points x2 (set); x1 is flat/[smooth]. [also: x1 is even/planar/level]; (x2 is a set of points at least sufficient to define the plane)
• canlu x1 is space/volume/region/room [at-least-3-dimensional area] occupied by x2. [also occupy (= selca'u)]
