Words spelled with -ae/-oe

British English words that are spelled with the double vowels ae or oe are just spelled with an e in American English:

British US
leukaemia leukemia
manoeuvre maneuver
oestrogen estrogen
paediatric pediatric

 

Note that in American English, certain terms, such as archaeology, retain the ae spelling as standard, although the spelling with just the e (e.g., archeology) is usually acceptable as well.
