The quality of being considered very important and deserving respect, often because it is sacred or inviolable.
Many people believe that the sacrosanctity of human life should be protected at all costs.
Sacrosanctity → It is formed from "sacro-" (from Latin "sacrare", meaning to make sacred) and "sanctity" (from Latin "sanctitas", meaning holiness or sacredness). The word "sacrosanctity" refers to the quality of being regarded as sacred and inviolable.
Think of something that is 'made sacred' ('sacro-') and has a quality of 'holiness' ('sanctity') — this helps you remember that sacrosanctity means something that is considered extremely sacred.
