A more thorough explanation:

Littus maris (lit-uhs mar-is) is a Latin term that means "shore of the sea." It has two meanings:

1. Ordinary tides or neap tides that occur between the full moon and dark of the moon.
2. The shore between the normal high-water and low-water marks.

Example 1: During littus maris, the tides are not as strong as during spring tides.

Example 2: The littus maris is the area of the beach that is covered by water during high tide and exposed during low tide.

These examples illustrate the two meanings of littus maris. Example 1 refers to the type of tides that occur during this period, while Example 2 refers to the physical location of the shore between the high-water and low-water marks.
