What does indefensibly mean?
Indefensibly is an adverb meaning in a way that cannot be defended or justified. It is used to characterize actions, decisions, arguments, and conditions as unreasonable, excessive, or morally indefensible. The adverb commonly appears before words such as harsh, cruel, restrictive, and disproportionate, as in “an indefensibly severe penalty.” Its wording is more direct and emphatic than neutral descriptions such as “very unfair,” making it especially appropriate for formal criticism, debate, and legal or political commentary. The related adjective indefensible is more commonly used when directly labeling a person, principle, or position, whereas indefensibly focuses on the manner in which something is done. Although it can refer to conduct that is literally impossible to defend, the word most often means that conduct lacks a sound moral, logical, or practical justification.

Sometimes the sharpest criticism is simply that a choice cannot be defended: indefensibly severe, indefensibly unfair, and therefore impossible to justify.

Where does indefensibly come from?
The word was formed in the 19th century by adding the suffix -ly to indefensible. Indefensible itself combines the Latin prefix in-, meaning “not,” with defensible, from the Latin defendere, “to defend” or “to ward off.” The same Latin root produced defense, defend, defendant, and defensive. The modern adverb preserves the sense of doing something in a manner that cannot be defended or justified.
