The syntax of the Kalvskarian language is mostly left-recursive (the exception is the use of scaffolding) and it is based in units called sintagms; in fact, the sentence itself is a sintagm.
Although prepositions are optional in theory, they are widely used because they avoid ambiguety. From a preposition, you can tell the kind of sintagm and its limits. The exception is the beginning of the simple sentence, where the preposition of the sintagm that forms the sentence can be omitted. Example: in bu buh man buh bus im nation es, we can ommit the prepositions to and la in the beginning and just say: buh man buh bus im nation es.
A particular type of sentece is the nominal predicate. When the core of the sentence is es (in English, to be), that core can have many modifiers introduced by prepositions meaning subject. Note that there can be many prepositions introducing what we call subject, each one with its own fine-grain meaning (subject, attribute). In the example, the two subjects are buh man and buh bus im nation.
For the questions, there are particular prepositions that mark the type of response we expect (yes/no, subject, direct object, owner, etc). However, the international use of the question mark has been accepted among the Kalvskarians, and they use it in their written texts.
EBCDIC Rules:
<sentence>::= <core sintagm>
<sintagm>::= <core sintagm> | <modifier sintagm> | <coordinate sintagm>
<core sintagm>::= [<preposition>] [<sintagm>] <core>
<modifier sintagm>::= [<preposition>] [<sintagm>] <modifier>
<coordinate sintagm>::= <sintagm> <scaffolding> <sintagm>
