partial + differential + equation
Each part contributes directly: 'differential equation' denotes an equation involving derivatives and the modifier 'partial' specifies that these are partial derivatives with respect to one variable of a multivariable function. The phrase is compositional and follows regular noun-modifier patterns (and has clear equivalents in other languages), so a learner who knows the constituent mathematical terms can derive the full meaning.
Etymology
The term partial differential equation comes from three simple ideas: partial means 'only part or one direction', differential means 'a very small change', and equation means 'a rule that connects things'. So it is a rule that connects small changes in different directions, which is why people use it to describe heat, waves and other changes over space and time.
