defender

No sé qué haya dentro, pero se va a defender.	I don't know what's in there, but it'll put up a fight.
No se va a defender solo, ¿no?	It's not gonna defend itself, now, is it?
Conocimiento preciso del asunto en el que se va a defender los intereses del cliente;	Knowledge of the matter said where you will defend the client's interests;
Por lo tanto, debemos centrarnos en cómo se va a defender ese interés común, sin olvidar la necesidad de respetar plenamente el principio de subsidiaridad.	We must therefore focus on the way in which this common interest is pursued, without forgetting the need for full compliance with the principle of subsidiarity.
Pero, dado que hay una base material, se da lucha de clases (o en la sociedad sin clases, lucha y debate) sobre qué concepción del mundo, qué principios, qué ética se va a defender y aplicar.	But, given that there's a material basis, then there's the class struggle—or even in classless society there's a struggle among people—about which world view, which principles, which ethics are they going to uphold and apply.
