'Mer' is a feminine noun in French, so it always uses 'la' (the) unless in expressions like 'en mer' (at sea) where the article is omitted.
'Mer' refers to a sea (partially enclosed by land), while 'océan' refers to a vast, open expanse of salt water covering a large part of the Earth's surface. For example, 'la mer Méditerranée' (the Mediterranean Sea) vs. 'l'océan Atlantique' (the Atlantic Ocean).
From Old French 'mer', from Latin 'mare', from Proto-Italic '*mari', from Proto-Indo-European '*móri' (sea, lake). Cognates include Italian 'mare', Spanish 'mar', Portuguese 'mar', and English 'marine'.
'Mer' is feminine in French and always used with the definite article 'la' unless in certain fixed expressions like 'en mer' (at sea). The plural 'mers' is rarely used except in poetic or technical contexts.
