ondersubordinating

Ondersubordinating is a linguistic term used to describe a pattern of clause embedding in which a subordinate clause itself contains another subordinate clause, creating deeper levels of subordination within a sentence. The concept is discussed in theories of syntax that analyze hierarchical structure and the limits of embedding across languages. In this view, subordination is not a single, flat relation but a nested arrangement where each embedded clause can itself govern one or more further dependent clauses through its own complementizers or subordinating markers.

Mechanisms and indicators of ondersubordinating include the use of multiple subordinating conjunctions or complementizers in sequence, as well as syntactic markers that signal different layers of dependency. In many languages, each layer may be marked by a distinct that, whether, if, or similar subordinators, and the permissible depth of embedding can vary. The phenomenon is of interest in studies of processing load and memory, since deeper embedding tends to increase complexity for comprehension and production.

Examples illustrate the recursive nature of ondersubordinating. For instance: I believe that the claim [that the project will succeed] is credible. Here the outer clause governs the belief, the first embedded clause introduces the claim, and the embedded clause within the claim adds another level of subordination. Another example: We suspected that [the rumor [that she had left early]] was true.

In comparative syntax, ondersubordinating helps explain cross-linguistic variation in how deeply clauses can be nested and how grammar encodes those layers. See also subordination, embedding, complementizer, and syntactic hierarchy.
