文化的背景
The phrase reflects the deep-rooted importance of 'Qiyas' (analogical reasoning) in Islamic and Arabic logic. It became a staple of modern formal discourse as a way to ensure administrative and legal fairness. It suggests that the speaker is educated and values objective standards over personal bias.
The 'Fairness' Hack
If you feel someone is being unfair, start your sentence with this phrase. It forces them to acknowledge their own logic before they can disagree with you.
Don't over-use it

What It Means
Imagine you are building a house. If you use a strong concrete slab for the kitchen, you would likely use that same slab for the living room to keep things level. In Arabic, على نفس الأساس works exactly like that but for ideas. It is a logical bridge. It tells your listener, "Since we agreed on Point A, we must apply the same logic to Point B." It is about intellectual and moral consistency. You are essentially saying that the rules of the game haven't changed just because the players have.
How To Use It
You use this phrase to connect two related scenarios. Usually, you state a fact or a decision first. Then, you introduce the second scenario using على نفس الأساس. It acts as a sophisticated transition. It’s perfect for when you want to sound persuasive and grounded. You aren't just giving an opinion; you are following a pre-established pattern. It makes your argument feel much harder to poke holes in because it relies on a foundation you've already built.
When To Use It
This is a powerhouse phrase for negotiations. Use it when discussing salaries, contracts, or even household chores. If your roommate washed the dishes because it was their turn, then على نفس الأساس, you should take out the trash. It’s also great for academic writing or professional emails. Use it when you want to show that your current request is reasonable because it matches a previous one. It’s the "fairness" button in the Arabic language.
When NOT To Use It
Avoid using this for purely physical or aesthetic comparisons. If you want to say two people look alike, don't use this. It’s for logic, principles, and actions. Also, don't use it in very high-energy, emotional outbursts where logic isn't the priority. If you are screaming in joy at a football match, this phrase will make you sound like a lawyer who accidentally wandered onto the pitch. Keep it for when you want to sound thoughtful and composed.
Cultural Background
Arabic culture places a high value on العدل (justice) and المساواة (equality in treatment). Using على نفس الأساس taps into this cultural respect for consistency. Historically, Arabic rhetoric and jurisprudence relied heavily on analogy (القياس). This phrase is a modern, everyday descendant of that tradition. When you use it, you are signaling that you are a person of principle who values logic over whims. It commands a certain level of respect in a debate.
Common Variations
You might hear people say بناءً على ذلك (based on that) or من هذا المنطلق (from this starting point). While they are similar, على نفس الأساس is more specific about the criteria being identical. In some dialects, you might hear على نفس المبدأ (on the same principle). However, the standard version is widely understood and carries a nice weight of authority across the Arab world.
使い方のコツ
This phrase sits in the sweet spot between formal and neutral. It is highly effective in professional writing and debates. Avoid using it for simple, non-logical comparisons (e.g., 'He is tall, and on the same basis, his brother is tall' is incorrect).
The 'Fairness' Hack
If you feel someone is being unfair, start your sentence with this phrase. It forces them to acknowledge their own logic before they can disagree with you.
Don't over-use it

The Power of 'Assas'
The word `أساس` means foundation. In many Arab cultures, having a 'good foundation' (أصل) is a huge compliment. Using this phrase subtly links your logic to that deeply respected concept.
