Can someone explain the use of で in this sentence: 今日も元気で過ごせたらイイよね


I'm having trouble getting the correct translation of the sentence because of
the で particle. I don't know if it's being used as a particle or the
imperative form of 元気.




The で is a particle. According to 明鏡国語辞典:

> で 〘格助詞〙  
>  ❹動作を行うときの **様態** を表す。「急ぎ足 **で** 歩く」「親子 **で** 出席する」「笑顔 **で** 答える」「土足 **で**
> 上がる」

The で expresses 動作を行うときの様態, the manner of an action, how or in what manner an
action is done.

In 「元気で過ごす」, 「元気で」 (vigorously, cheerfully, healthily) describes how the
action 「過ごす」 (spend the day) is done.

> the imperative form of 元気

元気 is a noun or na-adjective, so it has no imperative form, at least in the
modern Japanese grammar.
