Here's a breakdown:
* Scansion: This is the process of identifying the metrical pattern of a poem. It involves dividing the lines into metrical feet (units of stressed and unstressed syllables) and marking the stressed syllables.
* Scanning: In a broader sense, "scanning" could refer to a more general process of examining a poem for its structure and features. However, it doesn't have a specific technical meaning like "scansion."
Think of it like this:
* Scansion is the map: It helps you understand the rhythm and structure of the poem.
* Scanning is the journey: It's the act of looking closely at the poem to discover its features.
