Cette coiffure te donne un plus indéniable.
I've learned that there should not be an enchaînement between "un plus" and "indéniable" somewhere, which means it shouldn't be pronunced as [œ̃-ply-sɛ̃-de-njabl], but I don't know why. I mean here "plus" is a nuonnoun prounced as [plys] and "un plus indéniable" is a groupe rythmique, why shouldn't I connect the [s] in [plys] and [ɛ̃] in [ɛ̃denjabl]?
