Synonym discussion
Sense: noun/1
All four words refer to the mental act of making sense of something, but they differ in formality and connotation. 'Understanding' is the broadest and most neutral term — you can use it in any situation, from casual conversation ('I understand the instructions') to academic writing. 'Comprehension' is more formal and often implies a deep or complete grasp of complex material, such as a scientific theory or a difficult text. 'Grasp' suggests a firm, practical hold on the subject — you might have a 'good grasp of grammar' but still struggle with advanced literature. 'Apprehension' is the most intellectual and abstract, used mainly in philosophy or formal analysis ('the apprehension of moral truths'). For everyday use, stick with 'understanding'; in academic or exam contexts, 'comprehension' fits naturally; use 'grasp' when you want to emphasise solid, working knowledge.

Etymology
Comprehension comes from Latin comprehensio(n-), which is built from com- ('together') and prehendere ('to seize, to grasp'). The original image was of 'seizing together' — grabbing hold of something with the mind, much like the physical act of catching or gripping. In medieval Latin it also took on the sense of 'including, comprising', which explains why the same word can mean both 'understanding' and 'the quality of covering many things'. It entered English through French in the 1400s with the mental-understanding meaning, and the 'including' sense followed a few centuries later.
