Common Mistakes
- 1Confusing the Two Meanings: The most fundamental error is using one meaning when the other is intended.
- Mistake:
The team broke down the project last week, so now it's stopped.(Implies failure, but "broke down" here likely means they analyzed it.) - Correction:
The team broke down the project last week, so now they understand the tasks.(Meaning: simplified/divided) - Correction for intended meaning:
The project broke down last week due to lack of funding.(Meaning: failed/stopped) - Why it's wrong: Misapplying the meanings leads to complete miscommunication. Context is key.
- 1Incorrect Separability with Pronouns: A very common grammatical error. Pronouns must go between the verb and the particle when
break downis separable.
- Mistake:
Can you break down it for me? - Correction:
Can you break it down for me? - Why it's wrong: This violates the strict rule for separable phrasal verbs with pronoun objects. English prefers the unstressed pronoun earlier.
- 1Using
break downfor general physical damage: Learners sometimes overextend the "stop functioning" meaning to simple instances of breaking.
- Mistake:
I accidentally broke down my pen. - Correction:
I accidentally broke my pen. - Why it's wrong:
Break downfor objects implies a failure of complex internal mechanisms, not simple physical breakage. A penbreaks, a carbreaks down.
- 1Incorrect Tense Usage: Like all verbs,
break downconjugates. Remember the irregular past tense ofbreak(broke) and past participle (broken).
- Mistake:
My computer breaked down yesterday. - Correction:
My computer broke down yesterday. - Mistake:
The information has been breaked down. - Correction:
The information has been broken down. - Why it's wrong:
Breakis an irregular verb (break,broke,broken), andbreak downfollows this pattern.
