ma, mammy, maw:
All of these are used locally to mean mother.
“Couldny be better Ma!”
“Hey Maw, whit’s fur ma tea?”
Many Glaswegians are particularly sensitive to their mothers (apparently it’s admissible to pan fathers), and this has given much rise to barbs such as yer maw’s a big man, yer maws a brickie, yer mammy’s a bun and so on.
