Overview

Já encontrou uma nota de 20 dólares num par de jeans que não vestia desde o verão passado? Ou talvez estivesse a fazer scroll no TikTok e tenha tropeçado num vídeo do seu professor da primária a dançar um hit viral? Essa sensação de
encontrar algo por acaso
é exatamente o que come across significa.
É um daqueles phrasal verbs que o fazem parecer menos um livro de gramática e mais um falante nativo. Neste guia, vamos ver como usar come across sem que pareça estranho.
Na sua essência, come across é um phrasal verb. Se é novo no inglês, um phrasal verb é apenas um verbo (como come) emparelhado com uma preposição ou advérbio (como across). Juntos, criam um novo significado que não tem nada a ver com vir ou atravessar uma rua fisicamente.
Usa-se come across de duas formas principais. A primeira é encontrar algo ou conhecer alguém por total acidente. Não estava à procura, mas estava lá.
É o
Ups, olha o que eu encontrei!
da língua inglesa. A segunda forma é sobre primeiras impressões. Descreve como parece aos outros.
Por exemplo, se estiver numa entrevista de emprego no Zoom e estiver a usar calças de pijama (não se preocupe, todos já o fizemos), quer come across (parecer/dar a impressão) como profissional, mesmo que o seu gato esteja a atacar os seus pés debaixo da secretária.
Porque é que isto é importante? Porque usar a palavra find a toda a hora é um pouco aborrecido. Come across dá sabor.
Diz ao ouvinte que a descoberta foi uma surpresa. É a diferença entre
encontrei as minhas chaves
(que estava à procura) e
me come across (deparei-me) com o meu antigo GameBoy
(que já me tinha esquecido que existia).

How This Grammar Works

Este phrasal verb é inseparável. Esta é uma forma chique de dizer que não pode colocar outras palavras no meio. Não pode dizer
I came a book across
. Isso soa como se houvesse um erro na matriz. Deve manter sempre come e across colados um ao outro: come across + [a coisa que encontrou].
Funciona em todos os tempos verbais, mas só muda a parte do come. Across fica exatamente como está. É como um cão leal que nunca sai do lado do dono.
  • Presente: Eu costumo come across (deparar-me com) cafés giros nesta cidade.
  • Passado: Eu came across (deparei-me com) um tweet estranho ontem.
  • Futuro: Irá come across (deparar-se com) muitos desafios neste jogo.

Piada: Porque é que o estudante come across (atravessou/deparou-se com) a estrada? Porque encontrou um livro de gramática que não estava à procura do outro lado! (Ok, vou limitar-me a ensinar, prometo).

Perguntas frequentes (8)

Yes, but only if you find it by accident while doing something else. If you are actively searching for it, use `found`.

It is neutral. You can use it in a casual text message or a formal business report. It is very versatile.

`Stumble upon` is more informal and emphasizes the 'clumsy' or highly accidental nature of the find. They are very similar.

No. This is a common mistake. You should say `I came across a friend`. No 'with' is needed.

No, we don't usually use it in the passive. We don't say 'The photo was come across by me.'

Yes! You can `come across an idea` in a book or `come across a problem` in a project.

It comes from the idea of your path 'crossing' the path of the object or person by chance.

Yes, mainly for the 'impression' sense: 'He is coming across as very helpful today.'
