sentences:  The final element of "iudd" has the meaning of "lord", and is found in other Welsh names such as "Gruffydd" and "Bleidd[i]udd".However, in Middle Welsh (c. 1150s–1300s) the name was most commonly spelt as "Maredud" and "Maredudd"; "in Welsh, the accent is on the penult, and this leads at times to the elision of the vowel of the first syllable," producing an early variant "Mredydd", according to T.J. Morgan and Prys Morgan.Anglo-Norman scribes often used "e" for the first syllable and substituting the double "d" with a "th", producing "Mereduth".
