Explanation for the Usage of …ないで, …なくて, and …ずに

<div class='writeup-body'>In Japanese, なくて is a construction that combines ない (in its conjugation form, なく), with the conjunction particle て. This results in the same 'and' meaning as the standard て form, but with the negative meaning of ない. なくて can be translated as 'to not (A), and…', or 'not (A), and…', depending on what type of word it is used with.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>お金（かね）がなくて車（くるま）が買（か）えない。</div><div class='writeup-example--english'>I don't have money, and I can't buy a car.</div></li><li class='writeup-example'><div class='writeup-example--japanese'>あのケーキは甘（あま）くはなくてまずいです。</div><div class='writeup-example--english'>That cake is not sweet, and tastes bad. (は is frequently added between the stem form of adjectives and ない. Often, this is just for emphasis)</div></li><li class='writeup-example'><div class='writeup-example--japanese'>私（わたし）の車（くるま）は静（しず）かではなくてガソリンの減（へ）りも早（はや）い。</div><div class='writeup-example--english'>My car is not quiet, and runs out of gas quickly.</div></li><li class='writeup-example'><div class='writeup-example--japanese'>あれは犬（いぬ）ではなくて猫（ねこ）でもないです。</div><div class='writeup-example--english'>That is not a dog, and not a cat either.</div></li></ul>As discussed in our initial lesson about ない, there are two forms of this particular word. One form is an auxiliary verb, and is used with verbs. The other form of ない is an い-Adjective (形容詞（けいようし）), and is used with nouns, な-Adjectives, and い-Adjectives. The difference between these two, is that the い-Adjective form may have は in between it and the word it is connected to (では in the case of nouns and な-Adjectives). With verbs, due to ない being an auxiliary verb, this is not possible.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>この風呂（ふろ）は汚（よご）れはなくて、いつもいい匂（によ）いがする。</div><div class='writeup-example--english'>This bath is not dirty, so it always smells good.

(Implies a specific reason for not giving it to the brother)</div></li></ul></div></div>
