Questions & Answers about A comida é suficiente.
Because a is the feminine singular definite article, meaning the.
In Portuguese, it is very common to use a definite article where English might use no article at all. So a comida can mean:
- the food
- sometimes food in a general/contextual sense, depending on the situation
Here, a comida most naturally means the food.
Since comida is a feminine noun, the article is a, not o.
- a comida = the food
- o alimento = the food / the nourishment
É is from ser, and está is from estar.
In this sentence, é suficiente means is enough / is sufficient as a judgment or statement about the amount. Portuguese normally uses ser here.
- A comida é suficiente. = The food is enough.
Using estar here would sound unusual in most normal contexts. Brazilian Portuguese generally prefers ser suficiente rather than estar suficiente.
A rough way to think about it:
- ser = used for defining, classifying, or stating a quality
- estar = used for states or conditions
Even though enough feels temporary in English, Portuguese still usually says é suficiente.
