Common Pitfalls
One common confusion arises from the interchangeable use of “rock” and “stone.” While they are synonyms for boulder when discussing large rocks, their nuances become significant based on context: “stones” suggests small-to-medium pieces, often in formal or historical contexts. Additionally, “pebble,” due to its size implication, should not be used interchangeably with larger terms like “boulder” or “stone.”
