Colloquialisation describes the increasing use of speech-like features in writing, such as contractions (e.g., it’s, Mair 1997). At the same time, writers have also been avoiding certain informal devices, such as phrasal verbs (Rodríguez-Puente 2014): a seemingly opposite trend known as decolloquialisation.
Changes in the frequency of features typically linked to conversation or to formal writing provide evidence of several overlapping sociolinguistic processes that shape recent stylistic change. Some of these processes share common ground with colloquialisation, while others move in the opposite direction.
In my conference work (Abalo-Dieste 2023, 2024), I compare processes similar to colloquialisation with processes that contrast with them. For example, colloquialisation is closely related to conversationalisation, yet both contrast with monologisation.
