Regretful vs. Regrettable – Which is Correct?

The words regretful and regrettable are both valid adjectives in American English, but they describe different things. Regretful describes a person who feels regret, while regrettable describes an event, action, or situation that causes regret. Understanding this distinction is key to using them correctly.

Regretful or Regrettable – Which is Correct?

Both “regretful” and “regrettable” are correct words, but they are used in different contexts because they have distinct meanings. The core difference lies in what they modify: regretful describes a feeling experienced by a person, whereas regrettable describes something that is worthy of regret, often an action or circumstance.

The Best Trick to Remember the Difference

The easiest trick to remember the difference is to focus on the suffixes. Think of “–ful” as “full of” and “–able” as “able to be.”

• Regretful: Full of regret (describes a person’s feeling). If you are regretful, you are full of regret.
• Regrettable: Able to be regretted (describes something that evokes regret). If something is regrettable, it is able to be regretted.

• Positive: regretful (e.g., He was regretful.)
• Comparative: more regretful (e.g., She seemed more regretful than her brother.)

The adverbial form is “regretfully” (e.g., He regretfully declined the offer.).

Etymology of the word Regretful

“Regretful” comes from the verb “regret” and the suffix “-ful.” The verb “regret” itself entered English in the late 14th century, derived from Old French regreter, meaning “to lament, complain, bewail.” This in turn might have Germanic origins (related to “greet,” meaning “to weep”) or Latin (from ingratus, meaning “unpleasant”). The suffix “-ful” means “full of” or “characterized by,” making “regretful” mean “full of regret.”

How to Use Regrettable

“Regrettable” is an adjective used to describe an action, event, situation, or circumstance that is unfortunate, deplorable, or causes regret. It describes something external to the person that is worthy of regret, rather than the person’s feeling of regret. It often implies that something bad happened that could have been avoided or that one wishes had not occurred.

Example 1: The cancellation of the concert was a regrettable decision for many fans.

Example 2: It’s truly regrettable that such a talented artist chose to retire so early.

As an adjective, “regrettable” can also have comparative and superlative forms:

• Positive: regrettable (e.g., That was a regrettable incident.)
• Comparative: more regrettable (e.g., The second error was even more regrettable than the first.)
• Superlative: most regrettable (e.g., This has been the most regrettable series of events in my career.)

The adverbial form is “regrettably” (e.g., Regrettably, we must postpone the meeting.).

Etymology of the word Regrettable

“Regrettable” is formed from the verb “regret” and the suffix “-able.” The suffix “-able” (from Latin -abilis) means “capable of,” “worthy of,” or “able to be.” Therefore, “regrettable” signifies “capable of being regretted” or “worthy of regret.” Its usage became more common in English around the 17th century, following the establishment of “regret.”

Related Concepts

Understanding broader grammatical concepts can help solidify the distinction between words like “regretful” and “regrettable.”

• Suffixes: The suffixes “-ful” and “-able” are key to distinguishing these words. “-ful” typically indicates “full of” or “having the quality of” (e.g., beautiful, helpful), often describing a subjective state or characteristic. “-able” typically means “capable of being” or “worthy of” (e.g., readable, lovable), often describing an objective quality or potential of something.
• Adjectives Describing Feelings vs. Adjectives Describing Causes of Feelings: Many English words follow a similar pattern where one adjective describes someone’s feeling (often ending in -ed or -ful) and another describes the thing that causes that feeling (often ending in -ing or -able). For example, a person is bored, but the movie is boring. A person is ashamed, but the action is shameful. Similarly, a person is regretful, but the event is regrettable.
