Morphology

definite + integral

The phrase is compositionally transparent: 'definite' (specific, with stated limits) modifies 'integral' (the mathematical accumulation/area), so a learner who knows both words can infer an integral taken over a specific interval yielding a numerical value. This construction is also reflected in other languages (e.g. Spanish 'integral definida', French 'intégrale définie'), supporting predictability for learners.

Etymology

Definite integral comes from the simple idea of adding many tiny pieces to make a whole: the word integral means 'whole' and you can imagine summing thin slices under a curve. The word definite means the start and end points are 'fixed', so the calculation gives one number for the 'area' under the curve.
