Precisodeumtamanhomaior.
Preciso (verbo precisar + de)
‘Preciso’ is the first‑person singular of ‘precisar’, which requires the preposition ‘de’ before the object of need.
de (preposição)
Introduces the noun phrase that follows; without it the sentence is ungrammatical.
um (artigo indefinido)
Indefinite article used before masculine singular nouns.
tamanho (substantivo)
Means ‘size’; it is a masculine noun, so it takes ‘um’.
maior (adjetivo comparativo)
Comparative form of ‘grande’; it does not need ‘mais’ because ‘maior’ already expresses the comparative.

Cultural Tip
In Brazil it’s common to add ‘por favor’ to soften a request, especially when speaking to a salesperson. Avoid double comparatives like ‘mais maior’; ‘maior’ already conveys the comparative meaning.
