indeliberate

Done without thinking

Indeliberate means not done on purpose—unintentional or accidental.

The word is rare, with *unintentional* or *inadvertent* serving the same function in most contexts: The damage was indeliberate, caused by a falling branch rather than vandalism.

It can also describe actions taken without careful thought or planning.
