Adverbeja

Adverbeja is a term used in linguistic theory and in a constructed language of the same name to describe a specific adverbial derivation process. In Adverbeja, adjectives form adverbs by adding the suffix -eja, typically without altering the base form.

Origin and usage: The term was introduced to illustrate a straightforward, suffix-based pathway from adjective to adverb and to compare how languages encode adverbial meaning. It is commonly cited in typological discussions and language-design exercises.

Morphology: The derivational suffix -eja attaches to adjectives to create adverbs. Some dialects show allomorphs such as -ejo. Derivational morphology may permit multiple affix layers, yielding adverbs with nuanced intensification or modality. Stress generally shifts to the suffix in many varieties.

Syntax: Adverbs formed with -eja behave as modifiers of verbs and, less often, adjectives. In the standard word order of Adverbeja, SVO, adverbs typically appear near the elements they modify, though focus and discourse factors can reposition them.

Examples:

luma + -eja = lumaeja, meaning brightly

mora + -eja = moraeja, meaning slowly

rapa + -eja = rapaeja, meaning quickly
