Editing Vocative case (section)

[[Welsh language|Welsh]] lacks case declension but marks vocative constructions by lenition of the initial consonant of the word, with no obligatory particle. Despite its use being less common, it is still used in formal address: the common phrase {{lang|cy|foneddigion a boneddigesau}} means "gentlemen and ladies", with the initial consonant of {{lang|cy|boneddigion}} undergoing a soft mutation; the same is true of {{lang|cy|gyfeillion}} ("[dear] friends") in which {{lang|cy|cyfeillion}} has been lenited. It is often used to draw attention to at public notices orally and written – teachers will say "{{lang|cy|Blant}}" (mutation of {{lang|cy|plant}} {{gloss|children}}) and signage such as one right show mutation of {{lang|cy|myfyrwyr}} {{gloss|students}} to draw attention to the importance of the notice.
