The vast majority of evaluative constructions are formed by means of morphological strategies. An evaluative construction must include at least the explicit expression of the standard (by means of a linguistic form that is lexically autonomous and is recognized by the speakers of the language as an actual word) and an evaluative mark. Therefore, in the Italian word gattino ‘kitten, dear little cat,’ the standard is expressed by the lexical morpheme gatt- (which occurs in masculine gatto and feminine gatta), while the evaluative mark is the suffix -ino. A construction can be defined as evaluative if it satisfies two conditions, one relating to semantics and the other to the formal level. The first condition indicates that an evaluative construction indicates a deviation from a standard (or default) value without resorting to any parameter of reference external to the concept itself. The second condition indicates that an evaluative construction must include the explicit expression of this standard and an evaluative mark. Among the world’s languages, evaluative morphology has a quite uneven diffusion: Eurasian languages, and Romance languages in particular, show the highest degree of evaluative morphology diffusion, considering the number of word formation processes involved, the word classes they apply to, and the semantic categories they express. From a historical point of view, evaluative affixes reveal an unstable behavior: they are often subject to a renovation. As a matter of fact, present-day Romance evaluative affixes do not coincide with Latin evaluative affixes: they derive from affixes that in Latin had different functions from ‘evaluation’ or from non-Latin affixes. From a synchronic point of view, Romance evaluative affixes prototypically exemplify all the cross-linguistically more frequent properties of evaluative morphology: categorial neutrality, insensitivity to the word class of the base, prefix-suffix neutrality, and so forth.
