Phrasal Verb: Cut down on

This phrase is a "transitive" phrasal verb. That is a fancy way to say it needs an object. You must cut down on something. You cannot just say "I am cutting down." Your friend will ask, "Cutting down on what?" The phrase always stays together. You cannot put other words in the middle. For example, you cannot say "cut sugar down on." That sounds very strange to native speakers. Keep the three words side-by-side like best friends. The word cut is the only part that changes. You can use it in the past, present, or future. The words down and on never change. They are like the anchor of the sentence.

If you use a saw on a tree, you just cut down the tree. The word on changes the meaning to "less frequency." Also, do not use it for people. Saying you want to cut down on your brother sounds like a horror movie! Use it only for habits, substances, or expenses. Finally, avoid it in very formal legal documents. In a court of law, use the word "reduce." But for 99% of life, cut down on is better.

Many people forget the word on. They say, "I need to cut down sugar." This is the most common error. Without on, the sentence feels unfinished. It is like wearing shoes without socks. Another mistake is trying to separate the words. Native speakers never say "cut sugar down on." Keep the trio together. Some people also use the wrong verb form. Remember, the past tense of cut is still cut. Do not say "cutted." That is a grammar crime! Yes, even native speakers mess this up sometimes. Just remember: cut, cutting, and cut are your only options.

How is this different from cut out? This is a big question. Cut out means zero percent. If you cut out bread, you eat no bread. If you cut down on bread, you eat one slice instead of four.
