Diinlang 2.0: Prepositions Group 3

Version 1.

Supposedly, a number of languages such as Tok Pisin have only two prepositions. In practice I suspect there are a variety of workarounds and some other words or phrases serve as prepositions too.
With Diinlang we have a similar situation, in that the words “per” and “di” can be used for most prepositional needs. These are not the only prepositions in Diinlang, and the addition of “ad” and “po” greatly increases the flexibility of a learner’s vocabulary. From here it is but a short step to add words such as “in”, “eks”, “up” and so forth. The prepositions of Diinlang are a good place to start building your vocabulary.
The third group of prepositions are, unfortunately, still a work in progress. This page will hopefully see numerous updates, so check the version number.
To the prepositions learnt in groups one and two we can add the word “kom”, meaning “with”. We have already encountered this word as a conjunction, but it can serve as a preposition too. “As” is another word we have already seen in use that may act like a preposition. The meaning is the same as in English, but applications are a little wider.
Still open to change are our terms for BEFORE and AFTER. These have both spacial and temporal uses. The words selected may be “pre” and “pos”, respectively.
The remaining words in group three are still being developed. Words/concepts that need translation include:
AGAINST: Some conlangs have used “contra” or “anti”, and these may be valid Diinlang words due to their use in Internation Scientific Vocabulary (ISV). It would be desirable to have a more compact Diinlang word. Also, to my mind “contra” and “anti” have a different meaning to how the word is used in context such as “The brick is leaning against the wall.”
ALONG: As in “Move along the path”.“trans” is a possible candidate, and has ISV precedents, but I am not really happy with this.
ACROSS: as in “The black rod is across the white rod.” “Tran” has been suggested, but it may be a little too close to “trans”.
AROUND: In English this word can indicate a location, a course or an approximation: “I will be around the bandstand at around three. Go around the fair.”. The ISV-derived “sirka” can be used, but a more compact Diinlang term is also desirable.
ABOUT: “The bricks are about the ball.” I considered the Portuguese “por”, although this has many alternate uses and may be too similar to prepositions such as “per”.
BESIDE: Whether a specific word for this is needed has to be decided. Combinations of existing words may serve instead, for example “ad siy” = “to (the) side”.
OPPOSITE: A term or word for this needs to be determined.
PASS: A word that can combine with directives to create terms equivalent to “overpass”, “underpass”, “bypass” etc.
BEYOND: this use may already be served by the word “vong”, meaning “yonder”.
AT: The English word “at” is derived from the Latin “ad” , meaning “to”. A literal equivalent does not exist in many languages, so I have tried to avoid it in Diinlang. Alternate words include “ad (to)”, “on (on)” and “veng (near)”.
BY: is another word for which a variety of other words can be used instead. These include veng, on, per and di.
