Final answer:
The word that does not belong is 'perder' because 'costar,' 'gastar,' and 'vendor' are all related to transactions and economic activities, while 'perder' means to lose and does not share this context.
Step-by-step explanation:
The question asks which word does not belong among the following Spanish words: costar, gastar, vender, perder. To determine which word is the outlier, we need to look at the meaning of each word:
- Costar - to cost
- Gastar - to spend
- Vender - to sell
- Perder - to lose
When we examine these words in the context of their meanings, perder (to lose) is the word that does not belong. This is because costar, gastar, and vender all relate to transactions and economic activities. Costar refers to the price of something, gastar implies the action of spending money, and vender means to sell something for money.
On the other hand, perder is unrelated to commercial activities and refers to the loss, which could be of an object, a game, or something intangible such as time. Therefore, perder is not associated with the financial or transactional context established by the other three words.
