1) (noun) patronising someone; treating someone as somehow worse and making them feel bad 2) (verb) to patronise someone or to do something which is "below" you 3) There is no need for condescension. Treating others with condescension is rude (mind you, it's probably more natural to use an adjective here: "in a condescending way"). / I can't believe he condescended to visit us. (= ironic, used as a joke here - we think that person considers us as being worse than him, so he is doing us a favour by visiting us) By the way, the adjective condescending is probably used much more often than the noun/verb you mentioned. Examples: a condescending attitude / a condescending remark / be condescending toward someone. Also, on a day to day basis, the word "to patronise" is used more often than condescend, I feel. Examples: Stop patronising me. / I hate being patronised. (adjective: patronising, e.g. He's so patronising it makes me sick). 加油!
