What does complexness mean?
Complexness is a noun denoting the quality or condition of being complex — that is, of consisting of many interconnected parts or elements arranged so as to be difficult to analyse, follow, or resolve. It applies equally to tangible structures, such as machinery or architecture, and to abstract systems, such as arguments, institutions, or computer algorithms. In most contexts it functions as a direct synonym of the far more frequent complexity, but it remains comparatively rare, appearing mainly in formal, academic, legal, and technical prose where a writer prefers its straightforward '-ness' construction over the Latinate '-ity'. Its connotations are neutral to slightly weighty: describing something's complexness signals seriousness and difficulty without implying disorder or fault. The word derives ultimately from Latin complexus, 'an embrace' or 'a weaving together', through English complex. For general readers and most writers, complexity is usually the natural choice, but complexness remains a legitimate and precise alternative.

Etymology of complexness
Complexness is formed by adding the native English suffix '-ness', which turns adjectives into abstract nouns denoting a state or quality, to the adjective complex. Complex itself entered English in the mid-17th century from Latin complexus, the past participle of complecti, 'to entwine, embrace, or surround', literally 'to clasp completely'. Because '-ness' formations are transparent and mechanical, complexness emerged as soon as writers needed an abstract noun for the adjective; however, the older and more learned derivative complexity, built directly on the Latin-style '-itas' pattern, had already become entrenched, which explains why complexness has always been the rarer sibling.
How complexness is actually used
Complexness is markedly less common than its synonym complexity and can sound stilted in everyday prose. It survives chiefly in academic, legal, or technical writing, where some writers prefer it for its concrete '-ness' form.
