I have just come across an old cutting from the Irish Times. In his column Words We Use, Diarmaid O Muirithe explains the word shend, which is still used by some Ulster-Scots speakers in the Ards peninsula.
According to the Scots dictionaries it means 'to chide, reprove; to confound; to disgrace.' The word also has the meansing of 'mar, destroy, ruin' and from it we get the noun shendship, meaning 'ruin, confusion'.
A correspondent to Diarmaid recalled her mother saying, 'Don't dare go to church in that gaudy dress, you'll have us all shent.'
The word is from the Old English scendan, 'to put to shame, to injure.'
