I’m having troubles naming a concept. So you know how in football, you can be on offense, or defense? There’s kinda like…two sides there? Well, there might be things that apply only on offense, or defense, or maybe on both offense and defense.
What would you name the property of something that can be pertinent for [“offense”, “defense”, “both”]?
currently the word I’m using is “side”, but its not really a side. home or away would be a side. its a property of the game that flips and switches
only good metaphor I’ve been able to link to it is electricity - you can be positive, or negative, and it can switch. so “polarity.” Or a road, where you're going one direction, or another.
Sorry this is kind of ambiguous, I just have this suspicion there's a word that means this that I don't know.
