Obliged and obligated sound similar enough to be mistaken for each other. This article will help clear the different meanings and different English usages up and give you confidence in their use in the English language.
Obliged means to be indebted to someone for something they did for you or gave you. Obligate means to require someone to do something legally or morally and is common in American English. Obliged is more commonly used in British English today, although both are correct and have a slight variance in meaning. They both come from the verb “oblige” whose etymology includes the Latin obligare and Old French obliger.
