If you mean “is Esperanto English”, the answer is no, they’re pretty different, Esperanto combines elements of latin and slavic languages. If you mean “Isn’t English already an auxiliary language”, the answer is also no. English is a lingua franca, not an auxiliary language.
Esperanto is a romance-adjacent language using the Roman alphabet. It has its own grammar and phonetics, with rules that are flexible enough that a word-for-word translation from English or German will have a fairly correct sentence structure. As someone who speaks English, knows a little French, and has heard German, I expect it is closer to Spanish or Portuguese than English, but it isn’t just like those, either.
Isnt that english?
