Sometimes verbs have meanings that are very similar, but they differ enough to maintain separate usage cases.

Obligated and obliged are great examples of this. Both words refer to required actions, but they each have specific contexts that are just different enough that each word feels out-of-place when substituted for the other.

I will also demonstrate how to use a mnemonic device that will help you choose obligated or obliged when you need to use one of these words.

When to Use Obligated

What does obligated mean? Obligated is a verb. It means required to do something, especially when prescribed by legal or moral necessity.

Obligated is both the simple past tense and past participle form of obligate. It becomes a rough synonym of required, like in the phrase obligated responsibilities. Usually, though, it would be more common to use the noun obligations instead.

The verb obligate was first recorded in English in the early 16th century, and it is derived from a Latin verb with a similar meaning.

When to Use Obliged

What does obliged mean? Obliged is also a verb. It is commonly used in phrases like much obliged, where it means grateful or indebted. Obliged is also the simple past and past participle forms of its root verb, oblige.

As a verb, obliged has a similar meaning to obligated but without the legal or moral connotations. Instead, it connotes an action done with no expectation of a return favor.

If you attend a dinner party at a friend’s house, you might be obliged to send a thank-you note. You obviously aren’t legally or even morally required to send one, but common etiquette might make you feel obliged to thank your friend for hosting you.
