Lavisher is a word that denotes extravagance and generosity, particularly when it comes to spending money and resources. Some synonyms that come to mind include spender, philanthropist, and benefactor. A spender is someone who has a tendency to spend money freely without much consideration for savings or financial planning. A philanthropist, on the other hand, is a person who donates money or resources to charitable causes or for the greater good of society. Finally, a benefactor is someone who provides financial or other assistance to a person or organization in need. All of these terms are related to the idea of lavishing resources on others, but each carries a slightly different connotation.
