Variation in the Production of Dental Fricatives in English Dialects: Underlying Factors of a Present-Day Sound Change

Dental fricatives are amongst the rarest speech sounds in the natural languages found in the world (Jekiel, 2012) and have disappeared from most Germanic languages (Laker, 2014). However, the standard varieties of English still contain both the voiced and voiceless dental fricatives as phonemes. Although these phonemes are still common in e.g. Received Pronunciation (RP) and General American (GA) (Ladefoged & Maddieson, 1996), the dental fricatives are often replaced in other, non-standard varieties through processes such as th-fronting. The phenomenon of these contemporary changes in articulation has been studied, though a large portion of the research has been based mostly on sociolinguistic descriptions and discussing the phenomenon from this field’s paradigm (see e.g. Kerswill, 2003; Stuart-Smith et al., 2013) without thoroughly discussing other potential underlying phenomena that could cause the variation and change of dental fricatives in dialects: phonetic and phonological...Show moreDental fricatives are amongst the rarest speech sounds in the natural languages found in the world (Jekiel, 2012) and have disappeared from most Germanic languages (Laker, 2014).

This thesis explores some of the various ways the subfields of linguistics, historical linguistics, sociolinguistics, and phonetics, can work together to provide insights into the underlying factors influencing sound changes. By analysing the scientific literature concerning dental fricatives, the tentative conclusion was reached that, as dental fricatives do not have much phonemic function and are difficult to acquire and most Germanic languages have lost the dental fricatives, Britain could soon follow, especially if th-fronting loses its social stigma.Show less
