pro-bono

The term "pro bono" is a direct loanphrase from the Latin "pro bono publico", which means "for the public good". It entered English legal terminology as a shortened form, retaining the core Latin words. The phrase originally described professional work, particularly legal services, undertaken voluntarily and without payment as a contribution to the common welfare. Over time, its usage has solidified in English to specifically denote legal work provided free of charge, especially for the public interest or for those unable to pay, thus carrying forward the original Latin ideal of acting "for the good".

Structure: pro (for) + bono (good) - pro: Latin origin, a preposition meaning "for" or "on behalf of". In this compound, it functions as a prefix indicating "for". - bono: Latin origin, from the ablative case of 'bonus' meaning "good". In this phrase, it functions as a noun meaning "the good".
