～につれて

About

につれて is formal in tone, and is a combination of the に particle, and the て form of the verb 連つれる, "to be accompanied by". につれて is best translated as "as" or "with".

につれて can attach to dictionary form verbs, or to nouns. Nouns should be those that denote a change of some kind.

E.g. 日本語にほんごが上手じょうずになるにつれて、日本にほんでの生活せいかつも楽たのしくなってきました！ "As my Japanese improves, my life in Japan has also become fun!"

E.g. 医療いりょうの発展はってんにつれて、平均へいきん寿命じゅみょうも伸のびてきた。 "With the development of medicine, the average lifespan has increased."

につれて attaches to actions of gradual change and suggests a loose cause-and-effect relation with a second, following action.

「につれ」 is also possible, and is more stiff/formal in tone.

E.g. 学校がっこうが忙いそがしくなるにつれ、友達ともだちと遊あそぶ日ひが減へった。 "As school became busy, the days I met up with my friends decreased."
