necessitarão

Necessitarão is the third-person plural form of the Portuguese verb necessitar in the futuro do presente do indicativo, meaning "they will need" or "they will require." It appears with a subject in the third person plural and is used to express a future need or requirement.

Etymology and grammar: necessitar comes from the Latin verb necessitare, related to necessitas (necessity). In Portuguese it is a regular -ar verb and is typically used as a transitive indirect verb, requiring the preposition de before its complement (necessitar de). For example: Eles necessitarão de mais tempo. The form shown here corresponds to the future tense; other persons use analogous endings (eu necessitarei, tu necessitarás, ele necessitará, nós necessitaremos, vós necessitaríeis, eles necessitarão).

Usage and nuance: Necessitarão is common in formal or written contexts. It can be substituted by precisarão in many contexts, which is more frequent in everyday speech. Both convey a future requirement, but precisarão is often preferred for less formal discourse, while necessitarão may appear in official reports, legal language, or academic writing.

Examples:

- Eles necessitarão de apoio financeiro para concluir o projeto.

- Se a demanda aumentar, eles necessitarão de recursos adicionais.
