diaciddiollike

Diaciddiollike is a term used mainly in speculative linguistics and language-creation communities to describe a hypothetical morphological pattern in which a single morpheme encodes multiple grammatical categories through a combination of diacritics and affixal material. It is not a term used in mainstream typology and has no formal status in widely cited grammars.

The word appears to be a coinage from online conlang discussions, where it is sometimes presented as a portmanteau blending references to diacritics with a coined root form and the suffix -ike to indicate resemblance. Because it is largely used in hobbyist or experimental contexts, its precise definition can vary between authors and language projects.

Core features commonly discussed include the use of diacritic marks attached to a root or to an affix in a way that signals more than one grammatical category at once. In practice, a diaciddiollike form might be described as combining tense, aspect, mood, number, or voice within a single morphophonological package. Some proposals allow diacritics to attach to the base, to an infix, or to a suffix, while others emphasize alignment with a language’s phonology and orthography.

Usage and interpretation are highly context-dependent. In constructed languages, diaciddiollike forms are presented as a means of compact encoding and as a test case for how diacritics interact with affixal systems. They are generally not attested in natural languages and remain a niche concept within conlang design.
