What are some words you feel sound more right in both the American and British English?
I use a mix of the two depending on the word.
For example, I stand by pronouncing words like “Amazon” with an “ehn” sound at the end ovet an “ohn” sound, prefer spelling colour and flavour with a u, and also like using double Ls for words like travelling. Also, it is “grey”. (British English)
However, I pronounce Z as “zee”and call them fries rather than chips.
There are also spellings where I sort of alternate between depending on my mood, such as “meter” vs “metre”and“airplane” vs “aeroplane”
Are there any words that you think sound better in British and American spellings/pronunciations?
Advertisement sounds better in British pronunciation. Adver-tis-ment (/ədˈvɜː.tɪs.mənt/) as opposed to the American Adver-tize-ment (/ˌæd.vɚˈtaɪz.mənt/).
I’m British and have never said the first one you mentioned and don’t think I can recall hearing it. Nearly everyone one will use the second version - adver-tize-ment, although it’s most common to hear ad or ad-vert.
