Questions & Answers about O plano é flexível.
What is the structure of the sentence O plano é flexível?
The sentence follows a simple Subject–Verb–Predicate structure. O plano (“the plan”) is the subject, é is the linking verb (the third person singular of ser, meaning “is”), and flexível is the predicate adjective describing the subject.
What role does the definite article O play in this sentence?
O is the masculine singular definite article in Portuguese, equivalent to “the” in English. It specifies that the discussion is about a particular plan, which is why it is used with plano.
How do adjectives like flexível agree with the noun they describe in Portuguese?
In Portuguese, adjectives generally agree in gender and number with the noun they modify. In the sentence O plano é flexível, the adjective flexível matches the masculine singular noun plano. Many adjectives, including flexível, maintain the same form for both masculine and feminine singular contexts but will change in the plural (becoming flexíveis).
Why is the verb ser (shown as é) used instead of estar in this sentence?
The verb ser is used to describe inherent, defining, or permanent characteristics. In this context, saying “O plano é flexível” implies that flexibility is a fundamental quality of the plan. Estar would imply a temporary or changeable condition, which is not the intended meaning here.
How would the sentence change if referring to more than one plan?
If you were referring to multiple plans, the sentence would be adjusted for plural agreement: Os planos são flexíveis. Here, O becomes Os (plural definite article), plano becomes planos, é changes to são (the plural form of ser), and flexível becomes flexíveis to match the plural noun.
