Môn is the Welsh name o Anglesey, derivit frae the Breetish enisis mona, appearin first durin the Roman era as 'Mona': it is the Mona o Tacitus (Ann. xiv. 29, Agr. xiv. 18), Pliny the Elder (iv. 16) an Dio Cassius (62). It is cried Môn Mam Cymru ("Môn, Mither o Wales") bi Giraldus Cambrensis, for the claimit ability o the fertile land tae produce enough fuid for the whole o Wales. In reality, the claim was probably mair directit at an ability tae sustain Gwynedd. Auld Welsh names are Ynys Dywyll ("Dark Isle") an Ynys y Cedairn (cedyrn or kedyrn; "Isle o brave fowk"). Clas Merddin, an Y fêl Ynys (honey isle) are ither names. The Inglis name Anglesey is in fact derivit frae the Auld Norse, meanin 'Ongull's Island'. The alternative "isle (ey) o the Angles" is discreditit.
