Questions & Answers about shouhin o shuppinshimasu.
商品 means product, goods, or item for sale.
In this sentence, it refers to the thing being listed for sale. Depending on context, English might translate it as:
- a product
- an item
- goods
Japanese nouns usually do not show singular vs. plural clearly, so 商品 could mean a product or products, depending on the situation.
を marks the direct object of the verb.
Here, the verb is 出品します (to list for sale / to put up for sale), and 商品 is the thing being listed. So:
- 商品 = the item
- を = marks it as the object
- 出品します = list it for sale
So the structure is basically:
[item] を [verb]
= list [item]
