母のために

Mother. Mom is sporadically regionally found in the UK (e.g. in West Midlands English). Some British dialects have mam, and this is often used in Northern English, Irish English, and Welsh English. In the American region of New England, especially in the case of the Boston accent, the British pronunciation of mum is often retained, while it is still spelled mom. In Canada, there are both mom and mum; Canadians often say mum and write mom.In Australia and New Zealand, mum is used.
