Breach of precept term What is the Pali or Sanskrit term for a breach of a precept?
I have checked http://dictionary.tamilcube.com/pali-dictionary.aspx and found 
breach of morality defined as sīlabheda . Is there a broader or more inclusive term?
sīlabheda is not a common used term, I don't think. More common is sīlavipatti - transgression of morality. Another is vītikkama - transgression.


  tattha katamā sīlavipatti? yo kāyiko vītikkamo, vācasiko vītikkamo , kāyikavācasiko vītikkamo -- ayaṃ vuccati sīlavipatti. sabbampi dussilyaṃ sīlavipatti.
  (dhammasaṅgaṇī, nikkhepakaṇḍaṃ, suttantikadukanikkhepaṃ)


The common Pali term for an offence against the rules of the vinaya is āpatti. Another common, related word is dussīla, a person with bad moral character.
