Cave vs Grotto – What’s the difference?
The word grotto (Italian grotta, French grotte) comes from Latin grupta wich means cavern, crypt. The origin of the word cave can also be traced to Latin cava wich means concave, hollow. Now both terms are essentially interchangeable.
Grotto is more often used for smaller caves. Although, depending of their location and history, some of the largest caves in the world may still be called grottoes (ex.: Jeita Grotto).
Caves may be seen as darker and scarier or even related to cavemen, while Grottoes tend to be more decorative and magical with ornate features abound.
