質問: 違いは何ですか。 こんにちは! 質問があります。 早くと急いでと急ぎ違いは何ですか。
回答: 早く is modifying the noun, like an adverb. 急いで is the te form and also modies a noun, or you can use it in ます form and 急いでいる to be doing an action of hurrying. whereas the te form could be "hastily ..." 急ぎ is a connecting form as well, but it firectly attaches to another verb i believe. if i had examples i could explain it better.
