Mix Up in a Sentence: Meaning, Uses & Examples

    Cartoon children swap two name cards by mistake, showing mix up in a sentence as confusing one thing for another.

    Mix up is a separable phrasal verb with two everyday jobs: to confuse two things, as in “I mix up the twins,” and to combine things by stirring, as in “mix up the batter.” The object decides which sense is meant, and a pronoun object always lands between the verb and the particle.

    Mix up at a glance

    • Mix up is a separable phrasal verb; its forms are mixes up, mixed up and mixing up.
    • The two main senses are confusing one thing for another and combining things by stirring.
    • Typical objects are names, dates, documents, files or batches of ingredients.
    • Mix up sits in informal to neutral writing; the hyphenated noun mix-up suits news reports.
    • The commonest error is putting a pronoun after the particle: mix up them is wrong.

    What does mix up mean?

    Mix up is a phrasal verb meaning either to confuse two people or things, or to combine ingredients by stirring them together. The Cambridge entry for mix up records both senses, and the object separates them: you mix up two similar names, but you mix up a bowl of batter. Where the point is only to combine things, blend the flavours is the plainer verb, because mix up also carries the idea of a mistake.

    Sense Plain meaning Example sentence
    Confuse Fail to tell two things apart I always mix up those two streets.
    Combine Put ingredients together into one mixture Mix up the eggs and sugar first.
    Involve in trouble Get drawn into something undesirable He got mixed up with a betting ring.
    Noun: mix-up A mistake or confused situation A mix-up at the desk sent us to the wrong room.

    One limitation is worth stating plainly. Mix up never means solve or fix: a mix-up is the problem, not the cure. When two things are combined on purpose and no error is implied, mix, combine or blend is the more precise choice.

    Frequently asked questions about mix up

    Is mix up one word or two?

    The verb is always two words, as in mix up the paints. The noun is one hyphenated word, as in a booking mix-up. Writing the noun as mixup without a hyphen is a common spelling error that dictionaries do not list, so keep the hyphen in every formal document.

    What is the difference between mix and mix up?

    Mix means to combine things, usually on purpose, as in mix the paint. Mix up adds either an element of mistake, as in mix up two names, or a casual combine sense, as in mix up a cake. Choose mix when no error or separability is involved.

    Is mix up formal or informal?

    Mix up is informal to neutral, and it appears in conversation, emails and news reports. The hyphenated noun mix-up is common in journalism. In academic or legal writing, confuse or combine is usually the safer choice because the phrasal verb can sound casual.

    Can you say mix up them?

    No. When the object is a pronoun, it must go between the verb and the particle: mix them up. A full noun phrase may go either side, so mix up the paints and mix the paints up are both correct. The pronoun rule is the one to remember.
