Shannon (given name)
（重定向自Shannen）
Shannon ("wise river") is an Irish name, Anglicised from Sionainn. Alternative spellings include Shannen, Shanon, Shannan, Seanan, and Siannon. The variant Shanna is an Anglicisation of Sionna ("possessor of wisdom").
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".
