What does Tanto…quanto mean?
Tanto…quanto is used to say that two elements have the same amount or degree of something. In English, it is similar to as much as, as many as, or both…and when used with nouns, adjectives, or verbs. The structure adapts to the grammatical gender and number of the noun it refers to.
Basic idea
Use tanto…quanto when you want to compare equality, not inequality. For example, to say Maria studies as much as João, you use tanto…quanto because the amount of studying is equal.
Forms and agreement
The word Tanto must agree in gender and number with the noun it modifies. The common forms are:
tanto (masculine singular)
tanta (feminine singular)
tantos (masculine plural)
tantas (feminine plural)
When comparing actions (with verbs) or adjectives, you usually use the invariable adverbial form tanto followed by quanto. In those cases, no agreement is needed.
Summary of agreement
If the comparison targets a noun, match gender and number: tanto/tanta/tantos/tantas + noun + quanto/quanto(s)/quanta(s) + noun or + pessoa.
If the comparison targets a verb or an adjective, use tanto…quanto (tanto is invariable) or sometimes tão…quanto for adjectives/adverbs when comparing degrees.
Using Tanto…quanto with nouns
When comparing quantities of nouns, Tanto…quanto behaves like a determiner and must agree with the noun. The second part of the construction often repeats agreement to match gender and number, though many speakers use quanto invariable after the first phrase depending on structure.
Examples with nouns
tanto + masculine singular noun
Exemplo:
Ele tem tanto dinheiro quanto ela.
tanta + feminine singular noun
Exemplo:
Ela tem tanta paciência quanto o professor.
tantos + masculine plural
Exemplo:
Nós temos tantos livros quanto vocês.
tantas + feminine plural
Exemplo:
As crianças têm tantas perguntas quanto os pais.
Notes on placement
You can place tanto before the noun as a determiner. The second quanto usually precedes the element being compared or stands alone when the compared item is clear.
Using Tanto…quanto with verbs (actions)
To compare actions, use tanto + verb + quanto + verb or subject. In this pattern, tanto functions as an adverb meaning as much.
Examples with verbs
Ele estuda tanto quanto trabalha.
Ela fala português tanto quanto estuda inglês.
Você cozinha tanto quanto eu.
Note that verbs remain conjugated to match their subjects; tanto does not change.
Using Tanto…quanto with adjectives and adverbs
When comparing adjectives or adverbs, speakers often use tão…quanto as the parallel structure for degree comparisons, but tanto…quanto is also possible in some contexts, especially when the adjective follows a noun or is part of a phrase.
Preferable choice: tão…quanto
To compare qualities or intensity, prefer tão…quanto because tão is the adverb of degree. Example: Ela é tão inteligente quanto ele. However, you can see tanto…quanto used in similar meanings in informal speech or with noun-adjective combinations.
Examples that mix forms
Ele é tão alto quanto o irmão.
Nós corremos tanto rapidamente quanto vocês.
Short and full comparisons
Portuguese allows both short comparisons without repeating the second element and full comparisons that repeat it explicitly. Both are correct; use the short form for flow and the full form for clarity or emphasis.
Short comparisons
Ele tem tanto quanto ela. (understood: dinheiro)
Ela estuda tanto quanto. (understood: estuda quanto a outra pessoa)
Full comparisons
Ele tem tanto dinheiro quanto ela tem.
Ela estuda tanto matemática quanto química.
Negative forms and differences vs. mais/menos
Tanto…quanto is for equality. To express inequality, use mais…do que or menos…do que. With negatives, you can combine negation and tanto to deny equal degree: não…tanto…quanto to say not as much as.
Examples
João come mais do que Maria. (João eats more than Maria)
Ela não gosta tanto quanto eu. (She does not like it as much as I do)
No negative structure, the meaning is that the first element lacks the degree of the second.
Common pitfalls and tips
1. Agreement errors: Remember to match tanto with the noun in gender and number when comparing nouns. Incorrect: Ele tem tanta dinheiro. Correct: Ele tem tanto dinheiro.
2. Mixing tão and tanto: Use tão…quanto for adjectives/adverbs; use tanto…quanto for quantity or verb actions. Speakers sometimes mix them, so listen for context.
3. Redundant repetition: Both short and full forms are acceptable; avoid unnecessary repetition unless for clarity or emphasis.
4. Pronoun placement: When using pronouns, keep normal word order and verb conjugation. Example: Ela faz isso tanto quanto ele faz.
Advanced note: tanto quanto vs. tanto quanto + subjunctive
In certain comparative clauses that express doubt or hypothetical situations, you may encounter subjunctive moods in the verb following quanto, but this is rare in simple equality comparisons. Focus first on mastering declarative uses with the indicative.
Cultural and usage notes
Brazilian Portuguese speakers use Tanto…quanto frequently in everyday speech to compare routines, tastes, preferences, and quantities. In informal conversation, contractions and omissions are common, so you might hear shortened or elided forms. Formal writing and news use the complete forms with agreement.
Politeness and tone
Using tanto…quanto sounds neutral and factual. For emphasis or politeness, Brazilians often add adverbs or intonation. Example: Eu gosto muito tanto de café quanto de chá, or Eu gosto realmente tanto de café quanto de chá.
Regional variation
Minor regional differences exist in speech speed and contraction, but the grammatical rules remain consistent across Brazil. In fast speech you might hear tanto quanto pronounced quickly as a single phrase.
