What is the English meaning of 'Mar'?

The English meaning of 'Mar' is 'Ocean.' This term is derived from the Latin word 'mare,' which directly translates to 'sea' and has also come to refer more broadly to large bodies of saltwater. In various languages, 'Mar' is commonly associated with vast expanses of water like oceans, distinguishing it from other bodies of water such as rivers or ponds. Understanding the origins and usage of the term helps clarify its connection to large maritime settings, making 'Ocean' the most appropriate choice among the options presented. The other choices, while related to water bodies, do not share the same size or type characteristics associated with 'Mar' as it specifically refers to oceans.
