In reconstructions of Old English phonology, there is disagreement as to the phonemic realization of the symbol <h>. Some authors (Algeo (2010), Barber et al. (2009), Kuhn (1970)) consider it to be underlyingly glottal, while others (Bergs & Brinton (2012), Minkova (2014)) consider it velar. The objective of this paper is to determine the phonemic status of Old English <h> and its allophones. Additionally, it seeks to provide textual evidence for a diachronic variation in phonemic realization, as proposed in Minkova (2014). Following the theory of sound change presented in Lass & Anderson (1975), four texts from separate dates are analyzed for any textual indication of variation in pronunciation. Each occurrence of <h> is recorded with its environment and any other apparent factors that might influence realization. The number of environments per allophone would point out the most likely choice for the phoneme. If evidence for diachronic variation of this sort (referred to as “lenition” in Minkova (2014)) can be established, it can be inferred that the process might have occurred with other Old English phonemes, particularly the fricatives and plosives.
