Synonym discussion
Sense: noun/1
All four words refer to a female parent, but they differ in formality and the speaker's age. 'Mother' is the most neutral and formal — used in writing, introductions, or formal settings ('Her mother is a teacher'). 'Mom' is the standard informal term across North America, used by children and adults alike in everyday conversation ('I called my mom'). 'Mommy' carries a warm, childish tone and is used mainly by young children or by adults talking to young children ('Mommy, read me a story'). 'Mama' is also affectionate and informal, common in certain regional dialects or as a family preference ('Mama taught me this song'). 'Ma' is very short and casual, often used by older children or adults. Choosing the right word depends on the speaker's age, the relationship, and the social setting.

Etymology
Formed from 'mom' (a short, informal form of 'mother') plus the diminutive suffix '-y' (also '-ie'), which gives the word a gentle, child-friendly sound. 'Mom' itself comes from Middle English 'mome', a child's shortening of 'mother', which traces back to Old English 'mōdor', from Proto-Germanic '*mōdēr', and ultimately from the Proto-Indo-European root '*méh₂tēr', the source of 'mother' in most Indo-European languages.
