In Jainism, Atichar means a minor transgression or slip while observing a vow. There are different lists in the scriptures, with main variations by Digambar and Shwetambar traditions. A commonly cited framework is:

• Eight Atichar (Ashta Atichar) described under Darshanachara (conduct for seeing and understanding). These cover subtle faults in speech, mind, body, and worship that keep a vow from being perfectly observed. The text explains examples like improper conduct in thoughts, words, or actions related to vows and spiritual duties, and how they stain but do not completely cancel the vow. You can read more about these eight Atichar here .

• There are also sections in the tradition that talk about Atichars within other sets of vows (for example, five Atichar within certain Digpaṛimāṇ vrata discussions). These show that different Jain communities enumerate and describe Atichars in slightly different ways, but the core idea remains: minor lapses to be recognized and atoned for to keep the path toward liberation clear. See the same JainKnowledge discussions for more context.

If you want, I can summarize the eight Atichar items in simple terms from the sutra, or point out the exact verses and their meanings as per Digambar and Shwetambar readings.
