Ir + infinitivo (futuro imediato)

Artigo indefinido plural feminino
‘Umas’ is the feminine plural form of the indefinite article, used before a plural noun when the exact amount is not specified.

✕Common Mistakes
Vou comprar uns libras.
‘Libras’ is feminine, so the correct indefinite article is ‘umas’, not the masculine ‘uns’.
Vou comprar uma libra.
If you mean the British currency, keep the plural ‘libras’; using the singular ‘libra’ would refer to one pound, which sounds odd in this context.
Vou comprar a libras.
The definite article ‘a’ does not match the plural noun; use the indefinite article or omit it.

Cultural Tip
In Brazil, the most common places to buy foreign currency are casas de câmbio, banks, and some ATMs that dispense foreign notes. Rates can vary, so it’s wise to compare before exchanging. Remember that ‘libras’ can also mean weight; if you’re talking about a gym routine, you would need to clarify the context (e.g., ‘libras de peso’).
