“Grama”: When to Use the Feminine or Masculine in Portuguese

The correct use of “grama” depends on the intended meaning, as the same word has two grammatical genders in Portuguese. When referring to vegetation, it is feminine; when it denotes a unit of mass, the standard rule requires the masculine form and correct agreement.

When should “a grama” be used in the feminine?

When “grama” refers to low-growing vegetation, a lawn or grass, it is a feminine noun. You would therefore say “the garden grass has grown” or “the grass is wet”, keeping articles, adjectives and pronouns in the feminine throughout the sentence.

However, when the word names the unit of mass equal to one thousandth of a kilogram, it is masculine. The recommended forms are therefore “two hundred grams”, “the gram” and “five hundred grams of cheese”, with numerals and adjectives in the masculine plural.

The main distinction can be seen in the following examples:

• Garden: the grass grew after the rain.
• Cheese: I bought five hundred grams at the supermarket.
• Measurement: one gram is equal to one thousandth of a kilogram.
• Lawn: the grass was tall and wet.
• Agreement: two hundred grams, never the feminine equivalent of “two hundred grams”.

What do the standard norm and VOLP establish?

The gram is a unit of mass in the International System of Units, represented by the symbol “g” and equal to one thousandth of a kilogram. In this technical sense, dictionaries, prescriptive grammars and orthographic records classify the noun as masculine, regardless of its ending in a.

The Orthographic Vocabulary of the Portuguese Language records words alongside their grammatical information, helping speakers confirm the appropriate gender. Its guidance matches that of prescriptive grammars: the unit of mass takes a masculine article, whereas low-growing vegetation takes a feminine article and corresponding agreement.

How can you quickly tell which form of “grama” to use?

The easiest way to choose correctly is to look at what the word refers to. If the context involves an amount, a recipe, scales or packaging, it is likely to mean the unit of mass. If it involves a garden, field or backyard, it will usually refer to low-growing vegetation.

Garden is feminine, scales masculine

Context removes the uncertainty

If it grows from the ground, it is the feminine form of grama. If it appears in a recipe or on scales, it is the masculine form. The same principle applies to articles, numerals and adjectives connected with the word.

In a recipe, you should therefore write “add three hundred grams of flour”, rather than using the feminine form of “three hundred grams”. In a garden description, meanwhile, the correct construction is “the grass was tall”, because the adjective agrees with the feminine noun using appropriate agreement.

Use these associations to avoid mistakes:

• the masculine form of grama measures mass and appears in recipes and on packaging;
• the feminine form of grama grows in gardens, fields and public squares;
• write two hundred grams, three hundred grams and five hundred grams;
• use the feminine form for green, tall, dry or wet grass;
• check the meaning before deciding on grammatical agreement.

Why is this confusion so common among Brazilians?

The uncertainty arises because many Portuguese words ending in “a” are feminine, which leads speakers to apply that pattern automatically. Yet an ending alone does not determine grammatical gender, as shown by the masculine Portuguese nouns for “map”, “problem” and grama when it refers to mass.

In everyday speech, the feminine form is also used very frequently when discussing gardens, squares and sports fields. That familiarity strengthens the link between “grama” and the feminine, even when the context shifts to shopping, recipes or measurements of weight and quantity.

Here are some incorrect and correct examples:

• incorrect: I bought the feminine equivalent of five hundred grams of cheese;
• correct: I bought five hundred grams of cheese;
• incorrect: the masculine form of the garden grass is tall;
• correct: the feminine form of the garden grass is tall;
• correct: the packet contains only one gram of salt.

What simple rule can prevent mistakes for good?

Anyone consulting a list of the most common Portuguese mistakes will find similar questions caused by agreement based on appearance. Before selecting an article or numeral, identify the word’s meaning, since this step resolves the doubt more reliably.

In practical terms, remember one direct association: green grass grows in the garden in the feminine form, while the masculine form of grama measures mass on the scales. This straightforward difference prevents mistakes in recipes, shopping and formal writing, while maintaining clarity and the standard norm.
