I love the word solitude. It’s pure Latin of course, as many of the best English words are. A good Latin dictionary will give you a thought provoking array of possibilities to translate the noun solitudo-solitudinis (third declension feminine) ‘a being alone, loneliness, solitariness, solitude, lonely place, desert, wilderness, desolation, want, destitution, deprivation, orphanage, bereavement.’
