“Começar por” vs “Começar com” in Portuguese: Starting Point or First Step

Introduction

Portuguese learners often wonder about the difference between começar por and começar com. Both translate roughly as start or begin, but they signal different nuances: one emphasizes the first step or sequence, while the other highlights the point of origin or the instrument/element used. This article explains usage, grammar, examples, and cultural notes to help you choose the right form in Brazilian Portuguese.

Core distinction: sequence versus accompaniment

The clearest way to separate começar por and começar com is to think about what you want to express. Use começar por when you want to indicate the first action or step in a sequence. Use começar com when you want to say what accompanies the start, the material or person involved, or the way something begins.

Quick summaries

Começar por = emphasize the first step, initial action, or sequence order. It often introduces a verb or a clause that describes the initial move.
Começar com = emphasize the element, tool, person, or thing that marks the start. It usually pairs with a noun.

Grammar and structure

Both expressions use the verb começar followed by a preposition. The choice of preposition changes the structure that follows.

Começar por + verb/gerund/phrase

Começar por is frequently followed by an infinitive verb or by a clause that explains the first action. It frames the first step of a process or the first thing someone does.

Structure examples:
começar por + infinitive: começar por explicar, começar por dizer
começar por + clause: começar por que, começar por onde

Examples in context:
Vamos começar por revisar o material da última aula.
Translation concept: We will start by reviewing the material from the last lesson. Here the focus is the first action: revisar.

Ela começou por pedir desculpas antes de explicar o atraso.
The initial action is pedir desculpas; this is the first thing she did, then she explained.

Começar com + noun/people/thing

Começar com is followed by a noun that names what accompanies or marks the beginning. It can indicate the instrument used, the content that opens something, the person who leads, or even a specific item.

Structure examples:
começar com + noun: começar com água, começar com uma música, começar com João

Examples in context:
O evento vai começar com uma apresentação de dança.
The emphasis is on what opens the event: a dance performance.

Ele gosta de começar o dia com café e jornal.
This highlights the things that accompany the start of his day: café and jornal.

Common patterns and verbs that follow

Certain verbs or constructions pair naturally with each preposition. Recognizing these patterns helps you pick the correct form more quickly.

Typical uses of começar por

Use começar por when you describe:

– The initial action in a sequence: Começamos por chamar um táxi.
– A logical step-by-step procedure: Comece por lavar as mãos.
– A rhetorical device where the speaker lists the first argument: Vou começar por dizer o que aconteceu.

Typical uses of começar com

– The instrument or object at the start: Eles começaram o projeto com uma reunião.
– The person leading or opening an event: O congresso começou com a fala do reitor.
– Items or elements that accompany a beginning: A festa começou com bolo e música.

Examples comparing both in similar contexts

Seeing side-by-side examples will make the contrast clearer.

1) Organizing a meeting:
Vamos começar por discutir a pauta. — Focus: the first task is discutir a pauta.
Vamos começar com uma rodada de apresentações. — Focus: the meeting will open with a round of introductions.

2) Cooking or recipes:
Comece por picar a cebola. — The first step is chopping the onion.
Comece com azeite bem quente na frigideira. — Start by having hot olive oil in the pan; azeite is the element used at the beginning.

3) Telling a story:
Ele começou por explicar os antecedentes do projeto. — He first explained the background.
Ele começou com uma piada para quebrar o gelo. — He began with a joke to break the ice; the joke is the opening element.

Verb forms and conjugation notes

The verb começar conjugates like a regular -ar verb: começo, começa, começamos, começaram. The preposition that follows remains por or com regardless of tense or subject. Pay attention to the placement of por and com, which do not contract with the verb.

Examples across tenses:
Presente: Eu começo por explicar. / Eu começo com café.
Pretérito perfeito: Ela começou por pedir ajuda. / Ela começou com uma música triste.
Futuro: Nós começaremos por revisar os tópicos. / Nós começaremos com uma apresentação.

Nuances, emphasis, and contextual sensitivity

The difference can sometimes be subtle. In many contexts both forms may be grammatically possible but will change the nuance. Choosing one over the other shifts the listener’s attention to either the initial action or the starting element.

When both feel possible

Consider the sentence about starting a project. You can say either:

Começamos por definir os objetivos. — emphasizing the first step is defining objectives.
Começamos com a definição dos objetivos. — emphasizing that the project opens with the definition of objectives as an item or activity.

Both are correct; the first focuses on the step, the second on the element that opens the process. Use context and what you want to emphasize to guide your choice.

Idiomatic uses and fixed expressions

Some expressions are more fixed with one preposition. For example, to say start with a bang or a specific song, Brazilians commonly use começar com. To list verbs or steps, começar por is preferred.

Example fixed feeling: O filme começou com uma cena impactante. feels natural. For step-by-step instructions, comece por is the default: Comece por desligar o equipamento.

Common mistakes and how to avoid them

Beginners often mix the two because both translate to English start with or start by. To avoid mistakes, ask yourself two quick questions before choosing:

1) Am I naming the first action or step? If yes, use começar por.
2) Am I naming a thing, person, tool, or element that accompanies the beginning? If yes, use começar com.

Example error and fix:
Incorrect: *Comecei por o café.
Why incorrect: After por you expect a verb or clause, not a direct noun object like o café.
Correct: Comecei com o café. or Comecei por preparar o café.

Cultural and usage notes for Brazilian Portuguese

Brazilians use both forms naturally in spoken and written language. In everyday speech, começar com is common when talking about meals, parties, shows, and routines. Começar por is frequently used in instructions, academic contexts, and when listing procedures.

Register: Começar por can sound slightly more formal or procedural in some contexts, especially in written instructions or academic speech. Começar com is very common in casual conversation to describe what opens an event or habit.

Regional variations: The distinction is stable across Brazil; regional accents or slang do not typically alter the grammatical preference. What changes most is register and context rather than geography.

Practice comprehension through authentic examples

Reading real phrases and labeling the function of por or com will solidify understanding. Here are more examples with brief notes.

O curso vai começar por uma introdução teórica.
Note: por + initial action: a theoretical introduction is the first step.

O curso vai começar com atividades práticas.
Note: com + elements: practical activities will accompany the start.

Comecei por ler o contrato antes de assinar.
Note: por + verb phrase shows the first action in a sequence.

Note: com + noun shows what accompanied the start of the day.
