inside

inside: [16] Inside (a compound, of course, of in and side) was originally a noun, meaning ‘inner surface’ (‘Solomon builded the walls on the inside with Cedar timber’, Miles Coverdale’s translation of I Kings 6:15 1535), and it was not used as an adjective until the early 17th century – by Shakespeare, in fact. Adverbial and prepositional use are more recent still, from around the end of the 18th century.
=> side

inside (n.)

late 14c., ynneside "interior of the body," compound of in (adv.) + side (n.). The adjective is 1610s, from the noun. Inside job "robbery, espionage, etc., committed by or with the help of a resident or servant of a place" is attested by 1887, American English (also, late 19c., early 20c., "indoors work"). Inside track "advantage" is metaphoric because those lanes are shorter on a curved track. Inside of, in reference to time, is from 1839.
