The verbs "endure" and "bear" have similar meanings. They can both mean "tolerating" or "putting up with". For example, you could say, "I cannot endure his rude remarks!" or "I cannot bear his rude remarks". Both words can also be used to express the idea of "suffering without giving up" and "standing firm against attacks". For example, you could say, "She will have to endure great pain after her surgery" or " She will have to bear great pain after her surgery". The word "bear", however, can be used for more purposes than "endure". For example "bear" can mean simple things like "carry", "move", "produce", "give" and "posses". The expression "lean on" is different from "bear" and "endure". It is generally used when talking about "rest" or "emotional comfort" with support from someone. For example, you could say, "you can "lean" on me when you are tired" or "You can "lean" on me when you are sad". Hope this helps
