I’ve known for some time that the “o” was not used in the anniversary outline for adopt but then today wrote it in. Then i began to wonder why. The “o” is added in the simplified dictionary. The word adopt appears in the manual along side of adapt in the paragraph on the omission of the final t. Still, it is not a special form so why no “o”? Is it the same as in the word analysis where we drop un important vowels? Am i forgetting an obvious principle?
