The Usage of Comma in lists

Hello! 😊 Whether to include a comma before "and energetic" in the sentence depends on the style guide being followed and personal preference.

In this case:

• Including the comma (Oxford/serial comma):
  "The puppy was small, fluffy, playful, and energetic."
  This adds clarity and prevents potential ambiguity, especially in longer or more complex lists.
• Leaving out the comma:
  "The puppy was small, fluffy, playful and energetic."
  This is also correct and commonly used in informal writing or when following a style guide that omits the serial comma.

For most writing, it’s a stylistic choice. The Oxford comma is often preferred in formal writing or when clarity is essential. I hope this helps!
