x1=ta1 is a place-structure-dynamic tanru formed with x2=ta2 modifying (including possibly the place structure) of x3=ta3=c1=c2=b3=b2=b1, giving meaning x4=ta4=c3 in usage/instance x5=ta5=c4; x1 is a tanru with CLL place structure.
In the CLL Lojban standard (section 2.9), the tertau / final component determines the place structure. The language feature / extension terbricnetau allows tanru to modify the place structure rather than just the meaning, and also opens the place structure up a bit to context as well (e.g. with constructs for specifying dialects or dictionary modes - see also baunpli to ‘import’ a dictionary as well). When used / enabled, this allows affected tanru to function a little closer to lujvo, permitting context to allow some tanru to act more like idioms; indeed even the seltau may be a dictionary or qualified import name. Disabling this with terbristotau ensures tanru are ordinary CLL tanru with respect to place structure. ni'o Generally, scope is by default short (ve'i'ai) and affecting the preceding cmavo group like UI attachment / emphasis, but it can alternatively be medium scope or for the whole top-level bridi; and it can be with long scope for ‘sticky’ / permanent attachment, with ve'u'ai. Scope can also be precisely and explicitly declared with a full baunpli declaration, especially with x3. Even within a tanru, ke or bo-like connectors can be used to enable and disable this feature for multiple different specific tanru at the same time that are nested within a larger, composite tanru. With unspecified scope, generally by default ve'i'ai is used, which can affect a top-level bridi by appearing after «.i», except if scope in unspecified (e.g. there is no ve'i'ai-like expression or equivalent) and it appears alone with nothing else in a bridi, then a long-scope (sticky/permanent) of ve'u'ai may be inferred instead of ve'i'ai.
