Standard Welsh Place-names
Notes
The hyphen is used in Welsh place-names in order to aid pronunciation by showing that stress does not fall on the penultimate syllable. The stress falls on the final syllable of this name and therefore the final syllable is preceded by a hyphen.
The hyphen is also useful in this case in order to separate the consonants -t- and -h- since -th- is a singular letter in Welsh; it ensures that the name is not mispronounced.
