Is there a verb that means to make poor, such as a derivative form of the adjective poor? If not, what would be its best alternative?
You might try
- impoverish (to make poor; to deprive of strength, richness, or fertility by depleting or draining of something essential),
- pauperize (to reduce to poverty), or
- the verb form of beggar (to reduce to poverty or the practice of asking for charity)
all of which mean "to make poor."
