    This phrase is like saying 'Isn't it obvious?' You are not really asking a question. You are strongly stating what you think. You expect others to agree with you.

    This is like 'じゃねえか' but for い-adjectives. You use 'じゃねえか' for nouns and な-adjectives. For example, you say '静かじゃねえか' for 'quiet'. This form is also the question version of '〜くねえ'. That means 'it ain't good'.

    Don't use this when you need to be polite. For example, don't say it to your boss. This phrase is for casual talk. It sounds like a man talking. It is used for how things are now. You cannot use it for how things were in the past.

    〜い / 〜かった

    This is the basic form of an い-adjective. It describes a quality of something. You use it for present or past qualities.
