Language/English/Vocabulary/Words-with-different-spellings

Did you know that in English some words can be written in several different ways (they have different spellings).

Here is a list of the main words:

English words	Comment
Acknowledgment/acknowledgement	acknowledgment, without the middle e, is preferred in U.S. and Canadian English, while acknowledgement is preferred outside North America.
Adviser/advisor	In the U.S. and Canada, advisor is commonly used in official job titles, but adviser is still generally preferred over advisor in North America, and advisor is only marginally more common in American and Canadian English than in other varieties of English.
Aesthetic/esthetic	You can you use both. The main difference between aesthetics and esthetics is that "aesthetic" is used in British English while "esthetics" is used in American English. Aesthetics is a philosophical study that deals with the nature and appreciation of art, beauty, and taste.
Among/amongst	Among is the earlier word of this pair: according to the Oxford English Dictionary, it first appeared in Old English. The variant form, amongst, is a later development, coming along in the Middle English period. With regard to their meanings, there’s no difference between among and amongst.
