Overview: Two different meanings of acabar + preposition
The verb acabar by itself means to finish or to end. When you add a preposition, the meaning changes. The two common combinations are acabar com and acabar em. Each pattern answers a different question:
Use acabar com when you want to say someone or something puts an end to, destroys, or eliminates another thing. Think of it as transitive: there is a direct object that is ended.
Use acabar em when you want to say that something results in, ends up as, or finishes at a specific time or place. It describes an outcome, a consequence, or the final location/time of an action.
Acabar com: ending, destroying, or eliminating something

How to choose: quick decision guide
Ask one of these two questions to decide which to use:

Examples to apply the guide:
A empresa acabou com o projeto. -> Did the company end the project? Yes: acabar com.
A festa acabou em música e dança. -> Did the party end in that result? Yes: acabar em.
Common learner mistakes and pitfalls
Confusing ending an action with resulting in
Beginners often use the wrong preposition because both verbs involve the idea of an ending. Remember that acabar com takes a direct object that is terminated, while acabar em points to a result or final state.
Mistakes with passive meaning
When the subject is passive or an event simply ends, learners sometimes struggle. Compare:
O filme acabou às dez. -> The movie ended at ten (time). Use acabar with a time expression, no preposition required.
O filme acabou em tragédia. -> The movie ended in tragedy (result).
Overusing acabar com for neutral endings
Do not use acabar com to say that something finishes at a place. Say:
A estrada acaba no centro da cidade. -> Not acabar com.
More nuanced uses and idiomatic expressions
Acabar com in idioms and emphasis
Acabar com appears in expressions like acabar com a canseira (to get rid of tiredness) or acabar com o tédio. In spoken Brazilian Portuguese, people might say Isso acabou com a gente to mean That finished/defeated us emotionally or physically.
Acabar em with unpredictability or surprise
Acabar em is frequently used to highlight an unexpected result. Example: A viagem começou bem e acabou em confusão. This emphasizes the surprising outcome of confusion.
Using acabar sozinho for finish times and events
Sometimes acabar appears without a preposition to indicate when something ends. Use simple acabar with a time expression:
O show acabou às 23h.
A aula acabou cedo hoje.
Pronunciation and natural usage tips
In Brazilian Portuguese, acabar is pronounced a-ca-BAR with the stress on the last syllable in infinitive form. When speaking, native speakers often contract phrases: acabou com -> acabou com, but in fast speech the preposition may sound less emphasized. Pay attention to context and the object or complement that follows to choose the correct preposition.
Politeness and register
Both constructions are common in informal and formal registers. Acabar com can sound stronger when describing destruction or elimination, while acabar em is neutral for results. Use neither to be impolite; they are straightforward verbs without rude implications.

Cultural note: common Brazilian ways to express finishing
In Brazil, people use terminar, parar, and acabar interchangeably in some contexts, but each carries nuance. Terminar is more neutral for completing tasks or scheduled events, while acabar often implies an end that may be final, total, or with a particular result. Informal speech can favor acabar com for dramatic effect: A ressaca acabou com meu domingo.
