[Via Old French from Latin -tas, -tat-.]
Examples include anxiety (Latin anxietas), difficulty (Latin difficultas), honesty (Latin honestas), modesty (Latin modestus, keeping due measure), poverty (Latin paupertas, from pauper, poor); others are casualty, penalty and sobriety. Some, such as beauty, royalty, and warranty, were formed in French. However, travesty comes through French from Italian travestire, from Latin trans-, across, plus vestire, clothe. See also -ity.
