## 10.11. Space interval modifiers: FEhE

The following cmavo is discussed in this section:

 fe'e FEhE space interval modifier flag

Like time intervals, space intervals can also be continuous, discontinuous, or repetitive. Rather than having a whole separate set of selma'o for space interval properties, we instead prefix the flag fe'e to the cmavo used for time interval properties. A space interval property would be placed just after the space interval size and/or dimensionality cmavo:

Example 10.65.

 ko vi'i fe'e di'i sombo le gurni You-imperative [1-dimensional] [space:] [regularly] sow the grain.
 Sow the grain in a line and evenly!

Example 10.66.

 mi fe'e ciroi tervecnu lo selsalta I [space:] [three-places] buy those-which-are salad-ingredients.

Example 10.67.

 ze'e roroi ve'e fe'e roroi ku [whole-time] [all-times] [whole-space] [space:] [all-places]
 li re su'i re du li vo The-number 2 + 2 = the-number 4.
 Always and everywhere, two plus two is four.

As shown in Example 10.67, when a tense comes first in a bridi, rather than in its normal position before the selbri (in this case du), it is emphasized.

The fe'e marker can also be used for the same purpose before members of ZAhO. (The cmavo be'a belongs to selma'o FAhA; it is the space direction meaning north of.)

Example 10.68.

 tu ve'abe'a fe'e co'a rokci That-yonder [medium-space-interval-north] [space] [initiative] is-a-rock.
 That is the beginning of a rock extending to my north. That is the south face of a rock.

Here the notion of a beginning point represented by the cmavo co'a is transferred from beginning in time to beginning in space under the influence of the fe'e flag. Space is not inherently oriented, unlike time, which flows from past to future: therefore, some indication of orientation is necessary, and the ve'abe'a provides an orientation in which the south face is the beginning and the north face is the end, since the rock extends from south (near me) to north (away from me).

Many natural languages represent time by a space-based metaphor: in English, what is past is said to be behind us. In other languages, the metaphor is reversed. Here, Lojban is representing space (or space interval modifiers) by a time-based metaphor: the choice of a FAhA cmavo following a VEhA cmavo indicates which direction is mapped onto the future. (The choice of future rather than past is arbitrary, but convenient for English-speakers.)

If both a TAhE (or ROI) and a ZAhO are present as space interval modifiers, the fe'e flag must be prefixed to each.
