What this is about
Buying things without getting lost: prices (custar), paying (pagar), trying things on, colors that agree — and the two-letter words that make or break the deal (por, para, demais).
CUSTAR & money moves
| Quanto custa? · Quanto custam os sapatos? | singular custa · plural custam |
| Custou duzentos reais. | past: custou / custaram |
| Paguei com cartão. · à vista | by card · cash/up front |
| Tem desconto? | any discount? — always worth asking in Brazil! |
Trying on & deciding
| Posso experimentar? | can I try it on? |
| Qual é o seu tamanho? | your size? |
| Fico com a azul! | I'll take the blue one — ficar com = choose/keep |
| Caro demais! | too expensive — demais AFTER the adjective |
Colors — three rules
| 1 · -o/-a colors agree fully | o sapato preto · a camisa preta · os tênis brancos |
| 2 · -e and consonant colors only pluralize | verde/verdes · azul/azuis |
| 3 · noun-colors never change | rosa, laranja: as camisetas rosa |
Exceptions & details
1 · pagar POR: Paguei cem reais pela camisa — price is an exchange → por/pela (see "POR vs PARA").
2 · a calça is singular — one pair of pants: a calça jeans custa… (English "pants" logic doesn't apply).
3 · o tênis is singular too (one pair): quanto custa o tênis? Plural pairs: os tênis (same word).
4 · Past of pagar: paguei — the g→gu guard again.
