تكمن في
This pattern means that the real source, value, or essence of something is found in the phrase that follows في. It is useful for explaining where something truly lies, especially in reflective or formal writing. You can reuse it with abstract nouns such as value, meaning, strength, or happiness. Example: تكمن السعادة في تفاصيل بسيطة.
تكمن السعادة في تفاصيل بسيطة.
Happiness lies in simple details.
