x1 (experiencer/function) increases/gains/is incremented/augmented in property/quantity x2 such that it achieves/had achieved having that property at 'time' x3 (abstraction, number) according to standard x4
x1 is increasing in x2 for times/conditions determined by context (use ca, va'o, vel sim. in order to specify when increase occurs); times/conditions of increase are not necessarily those of attainment of that property (which is specified by x3). If an abstraction is submitted to x3 then the time of event of x1 achieving/attaining property x2 occurs exactly when/simultaneous with when/if the abstraction occurs (if it is an event) or is true (if it is a proposition, notion, truth value, idea, etc.); since it is increasing in that property and achieves it at that time, if the time determined by context is that determined by x3, then for times slightly later than that time will also have x1 having that property but times slightly earlier than that time will not. Numbers submitted to x3 determine the lesser/earlier endpoint of a semi-infinite interval through time such that attainment occurs throughout the interval. If a number is submitted to x3, the options are only li ni'u, li no, li ma'u, and li ni'u/ma'u ci'i; li ni'u ci'i being submitted means that x1 has always been/had x2, it just happens to be increasing in this property too (at the time specified by context); li ni'u (which is taken to be a finite number) means that there was a time prior to the time specified by context such that x1 was/had x2 but such has no always been the case, and also that at the time specified by context, it is increasing in this property; li no means that at the time specified by context, x1 has just attained being/having property x2 and it is also increasing in this respect; li ma'u (which is taken to be a finite positive number) means that x1 is increasing in property x2 at the time determined by context and that it has not yet (at that time) but will eventually (a finite and positive amount of time later) been classified as having that property properly according to x4; li ma'u ci'i means that x1 is increasing in x2 at the time specified by context but that it will never actually manage to achieve having that property according to x4, even if it asymptotically and strictly monotonically approaches that status. The time specified in x3 need not be the time of when x1 is increasing in property x2 (which is specified via ca or the like, in the bridi). "Time" in the sense of x3 is rather general; for example, it can also just be conditions which were satisfied when attainment is true (such as a subset on which a mathematical function is positive); it is generally an 'IF' statement (id est: attainment might occur at other times or under other conditions). For example, humans, normally, always increase in oldness/age (the context-determined time/conditions of increase in age is (those throughout) the entirety of their life), but are not actually considered old until they reach some age (specified by x3).
