What does es mean?
"Es" is the plural of the letter "e," used when counting or referring to multiple occurrences of that letter — for example, noting how many es appear in a given word. Writers sometimes render it as "e's" with an apostrophe for clarity, but "es" is acceptable where no ambiguity results. A second, specialized sense belongs to music: in German nomenclature, "Es" names the pitch E-flat, a convention familiar from European classical scores, where notes such as Es-dur denote E-flat major. Outside these contexts, "es" rarely stands alone as an English word, and readers may momentarily mistake it for the letter "s" spoken aloud, since both are pronounced identically. Its usefulness lies mainly in editorial, linguistic, and typographic discussion, where one needs to talk about letters as letters rather than use them to spell words.

Etymology of es
As the plural of "e," "es" derives simply from the name of the Latin vowel e, adopted into English through the Roman alphabet. Its musical sense comes from German practice, in which note names follow the same letters as English but add "-s" for flat and "-is" for sharp; hence "Es" for E-flat. This German convention has been standard in Central European music theory since at least the eighteenth century.
How es is actually used
"Es" is most often written with an apostrophe ("e's") in informal contexts, though style guides vary; without the apostrophe it is standard when no confusion with the word "as" or "is" arises. The musical sense is capitalized in German usage and is essentially confined to discussions of German-language scores.
Easily confused with es
"Esse" is a Latin-derived philosophical term meaning "being" or "essence," whereas "es" is simply the plural of the letter e.
"Es" can be confused with the letter S, which is pronounced /ɛs/; as a headword, however, "es" refers to multiple instances of the letter e.
