I've seen that English dictionaries contain a number of Spanish-imported words that contain the character ñ, such as piñata, piña colada and jalapeño. You find the same sound in other languages, such as French and Italian (the gn group as in the Italian word pugno), but that gn group does not represent the same sound in English (gnome, sign) where it represents just an n sound.
So I was wondering, does the sound the ñ character represents exist in any native English word? Take as "native" a word that was already present in English dictionaries in the 18th century that didn't come from a Latin-derived language. If there are still none, what were the closest approximations to that sound?
