abbaubarer

Abbaubarer is a fictional term used in speculative linguistics to describe a hypothetical morphophonemic pattern observed in constructed languages. In this imagined framework, abbaubarer designates a regular interaction between stem-internal vowel quality and affixation, where the vowel alternates in certain inflectional contexts and the alternation propagates to adjacent consonants, creating linked allomorph pairs. It is not recognized in established linguistic literature and is used here for illustrative purposes within a conlang or theoretical exercise.

Etymology and origin of the term are not fixed in any canonical source. The name appears to be a constructed compound, likely chosen to evoke European-language phonotactics and to signal a sui generis pattern rather than a label borrowed from existing typologies. Different conlang writers may offer varying etymological backstories, but there is no single authoritative origin.

Definition and typology. Abbaubarer typically refers to a stem-based vowel alternation conditioned by the presence of a specific suffix or set of suffixes. The pattern is described as regular within a given language variety, though its surface realization can vary by phonological environment. Key features commonly cited include: a predictable vowel quality shift within the stem across forms, coupling between this shift and an adjacent consonant cluster, and a distinct cross-form alternation that separates two or more allomorph families. Some treatments distinguish strong/weak instances or local vs. long-distance triggering, but all remain hypothetical constructs used to explore morphophonemic possibilities.

Example (fictional). In the constructed language Eldarin, the verb stem tal- alternates between ta- and te- when the past tense suffix -ar is attached, and the consonant following the stem undergoes a mild palatalization, yielding tevar, while talar remains ta-lar in other forms.
