ßig

äßig is not a standard standalone word in modern German. There is no widely recognized meaning, grammatical category, or productive function for the morpheme sequence -äßig in contemporary German usage. In formal reference works, the combination is not described as a living suffix that forms new words, and dictionaries do not list it as an independent affix.

In practice, encounters with the sequence are typically due to appearance inside longer words, or as a result of misspelling or typographical error. Words with similar letter patterns, such as lässig (casual, relaxed) or lästig (burdensome), are real German words but do not attest to a productive -äßig suffix. The similarity in spelling can contribute to occasional confusion or mistaken analysis, especially in informal writing or quick-reading contexts.

If -äßig appears in a text, it is generally advisable to inspect the surrounding context to determine whether the intended word is a standard form (for example, lässig) or another well-established adjective. As a matter of linguistic description, -äßig is not considered a productive or widely attested suffix in modern German morphology, unlike established endings such as -ig, -isch, or -lich.
