Concede means Admit. I've never really seen "Concede Victory" but I have seen "Concede Defeat" they don't mean the same thing. "They conceded defeat." Meaning they admitted that they lost. No one would necessarily need to "admit" victory, because it's usually pretty evident.

There are multiple words, a lot more than people can really just think of until they use it in a sentence. Like, I just thought of the word: target. It can be used as a verb in the sentence "Target that." Like a command, I'm telling you to take aim at something. Or as a noun, I can say "Shoot that target." Target is now the noun, as a thing. Shoot is the verb.

Very much so. A lot of jobs won't hire people beyond manual labor or remedial work unless that person has a degree. Going to college = Degree = Good Job.

Purpose is like intention, you intend or purpose to do something. Target can be an actual object, like a shooting target. Goal is something you wish to obtain or do. My goal is to learn Chinese. Aim is similar to goal. I aim to learn Chinese, or it can be used as a verb. Aim at the target. Objective is something you want to do. My objective is to learn Chinese. So, they are all really similar and will be understood the same way. I purpose I will learn Chinese. My target is to learn Chinese. My goal is to learn Chinese. My aim is to learn Chinese. My objective is to learn Chinese.

Plan means to make the intention to do something. Like "I plan to pay the phone bill." Scheme means an elaborate plan. Like "Ron started to scheme a plan that would ultimately enslave the world."
