reverence is a feeling of admiring and respecting somebody or something very much, a formal word that the Oxford Learner's Dictionary illustrates with reverence for nature, for elders, and for human life.
Dictionary.com defines the feeling as deep 📝respect tinged with 📝awe, giving veneration as a synonym and contempt as an antonym. Beyond the feeling itself, it lists the outward manifestation of that feeling, as in paying reverence; a gesture indicative of deep respect, such as an obeisance, bow, or curtsy; and the state of being revered, or treated with respect tinged with awe. With an initial capital letter, Reverence is a title used in addressing or mentioning a member of the clergy, usually preceded by "your" or "his". The word also works as a verb meaning to regard or treat with reverence, or to venerate.
The etymology carries the same element of awe. Oxford traces reverence to Middle English, from Old French, from Latin reverentia, from revereri, "stand in awe of", which joins the intensive prefix re- to vereri, "to fear".
