Learn Dutch: Er ligt grind naast het koraal. - There is gravel next to the coral.

You could say Er ligt wat grind naast het koraal. In this context, wat acts as an unstressed word for "some" or "a little" (een beetje). Adding wat before uncountable nouns like grind (gravel) is very common in Dutch to indicate an unspecified amount.

Why do we use ligt (lies) instead of is here?

Dutch strongly prefers positional verbs over the verb zijn (to be) to describe physical locations. Because gravel (grind) forms a flat, shapeless mass resting on the ground, it "lies" (ligt) rather than "stands" or "sits".

Why does the sentence start with Er instead of just saying Grind ligt naast het koraal?

Dutch uses er to introduce an indefinite subject (a subject without "the" or "this", like just "gravel" in general). Starting a sentence directly with an indefinite subject sounds awkward in Dutch, so we use the Er + verb + subject structure. This translates exactly to the English "There is..." structure.

Is the word grind pronounced like the English verb "to grind"?

No, it sounds quite different. The Dutch g is the typical throat sound, the i sounds like the short "i" in the English word "hint", and because Dutch words ending in d are pronounced with a "t" sound, the whole word ends up sounding like "grint".
