From taggare to blessare: verbal hybrid neologisms in Italian youth slang

Hybrid neologisms, formed directly within the language through various operations of word derivation and formation (Aprile, 2005) and characterised by the use of non-native structures, constitute a diverse system of phenomena and a significant part of contemporary Italian (Dardano, Frenguelli, Perna, 2000), with a growing influence on this linguistic system (Frenguelli, 2005; Giovanardi et al., 2003).
This contribution aims to investigate the phenomenon of verbal hybrid neologisms formed from a non-native morpheme, derived from an English verb, through the analysis of their diffusion in youth slang on social media, as the creation and dissemination of Anglo-Italian neologisms and pseudo-anglicisms can be the result of a bottom-up Anglicization (Lubello, 2014: 73).
Due to the fact that documenting the language evolution brought by the introduction of neologisms can be challenging in identifying and classifying new formations, but also in representing their meanings, we propose a methodology to support the discovery and the semantic description of neologisms.
As the first step, using the NLTK Python library, we extract the complete list of single-word English verbs from WordNet and apply a set of manually defined derivative rules to create the hybrid patterns. In Italian, hybrid verb neologisms are usually formed applying the 1st pattern conjugation, represented by the highly productive inflectional morpheme -are in the infinitive form. The derivative rules, accounting for the process of morphological blending, include any adjustment rules pertaining to Italian word formation that depend on the type of lexical morpheme used as root. Thus, for instance, monosyllabic verbs ending with a consonant and a vowel are adjusted by an elision of the final vowel and the doubling of the remaining consonant, like lovvare from love (it is worth stressing that this adjustment for monosyllabic verbs is not consistent, as it might be influenced by an interference with native words, e.g., zonare from zone).
From this procedure, we obtain a list of hybrid formations which present different statuses according to some dictionaries, e.g., Treccani dictionary: i. The formation is already recorded into dictionaries (e.g., taggare); ii. The word has been already identified but not included in dictionaries (e.g., shippare described in the Treccani Web portal in 2019); iii. The word is not present in dictionaries and has not been discussed in the Treccani Website (e.g., blessare and lovvare). Besides these types, we also identify another group that presents an overlap with native forms, e.g., zappare that can be the results of a neologism formation from zap o a native form which means hoe the ground (for the sake of this work, we do not consider the overlapping formations, as we would need a deeper semantic analysis to distinguish native forms from neologism usages).
The list of hybrid verbs are employed in combination with some of the hashtags related to the most popular reality shows and TV programs among young people to extract tweets and create our corpus. Indeed, the practice of commenting on reality shows and TV programs through social networks is widespread, especially among the youth, as evidenced by the daily trending topics published by the social media formerly known as Twitter (now X).
We refine the collected data on the basis of the number of occurrences of each candidate and apply a multidimensional approach to describe the candidate semantics. For the most widespread occurrence, e.g., shippare, we use an unsupervised approach, i.e., Latent Dirichlet Allocation - LDA (Blei et al., 2003), to obtain natural clusters for such occurrences. LDA allows for observing the data based on spontaneous aggregations, not decided a priori. It is commo
