Shannon (given name)

Common card · No. 459973

Shannon is an Irish name, Anglicised from Sionainn. Alternative spellings include Shannen, Shanon, Shannan, and Siannon. The variant Shanna is an Anglicisation of Sionna. Sionainn derives from the Irish name Abha na tSionainn for the River Shannon. Because the suffix ain indicates a diminutive in Irish, the name is sometimes mistranslated as 'little wise one', but means 'possessor of wisdom'. Some derive the denomination of Shannon (Irish: Sionnain) from the phrase sean-amhan or "old river." Another reported derivation is from Ó Seanaigh, "descendant of Seanach", which yielded the surnames Shanahan and Shannon.
