Someone who is irreligious is against religion, or has no religious feeling. The word can describe a person, a book, a joke, or a whole time in history.

Someone who is irreligious一個irreligious的人 is against religion反對宗教， or has no religious feeling或沒有宗教情懷。The word can describe a person, a book, a joke, or a whole time in history這個字可以形容一個人、一本書、一個笑話，或整個歷史時期。

It is a fairly careful, bookish word. It is stronger than just “does not go to church”: a person can skip services and still feel religious; an irreligious person does not have that feeling, or pushes against it.

It is a fairly careful, bookish word它是個相當講究、書面的字。It is stronger than just "does not go to church"它比「不上教堂」的意思更強烈：a person can skip services and still feel religious一個人可以不去做禮拜，但心裡還是有宗教情懷；an irreligious person does not have that feelingirreligious的人沒有那種情懷， or pushes against it或還會反對它。

Though actually, English also has words like non-religious and secular, which often mean “not tied to a religion” without the extra bite of being opposed. Irreligious can cover both “has no faith” and “is hostile to faith,” so you have to hear the tone.

Though actually不過其實， English also has words like non-religious and secular英文還有non-religious和secular這樣的字， which often mean "not tied to a religion"常常意思是「跟宗教沒有掛勾」， without the extra bite of being opposed沒有反對宗教那種額外的火氣。Irreligious can cover both "has no faith" and "is hostile to faith,"Irreligious可以同時涵蓋「沒有信仰」和「敵視信仰」， so you have to hear the tone所以你得靠語氣去聽出來是哪一種。
