– One is used predominantly in British English and the other one is used in American English.
– Americans pronounce “mom” as /ma:m/, while the Britons pronounce “mum” as /mʌm/.
In every given community, it has been noticed that the names given to women who are old enough to give birth to chilren vary. Children are not also left out in the parade of name calling.
There are different names children call their mothers by. While some prefer mama, mother, mommy, mummy, others prefer to use the shorter form which is either mom or mum.
Out of curiosity, I decided to look up both words in the dictionary and checkout if “mom” and “mum” mean the same thing and I was able to make two discoveries.
Firstly, both of them are different and the first difference between them is just like the difference between “labour” and “labor”, “colour” and “color” and “honour” and “honor”. One is used predominantly in British English and the other one is used in American English.
In line with that, “mum” is used predominantly in British English while “mom” is used in American English.
However, unlike “labour-labor, Colour-color, honour-honor”, there is not only a difference in spelling for “mom-mum”, there is also a difference in the pronunciation.
Americans pronounce “mom” as /ma:m/, while the Britons pronounce “mum” as /mʌm/.
It should be noted that even though “mom” is used predominantly in American English, there is now a relative frequency of its appearance in British literature.
Now that you know the difference, which would you rather stick to? Mom or Mum?
