 note = {筆者は四つの第二言語の習得を経験してきた。二つ目の第二言語だけは驚異的なスピードで習得することができたが， 他の三つは必ずしもスムーズなものではなかった。習得がスムーズだったものとそうではなかったものの相違点を見つけ， そこから考察を重ね，母語獲得と第二言語習得の説明に有効だと思われる四つの仮説を得た。In this paper, I examined the acquisition of four languages with which I have personal experience other than  my first language, and determined that these experiences may be classified into two types: those that could be acquired without difficulty and those whose acquisition entailed difficulty. Next, the differences between these were examined to generate several hypotheses that may be useful in first-language acquisition as well as second-language acquisition.},
