Enter The Market

Question

I have some question about the usage of the verb "enter":

1. New companies entered the market.
2. New products entered the market.

According to definition 2 from this dictionary for "enter":

def 2: to start to take part in a particular activity or to work in a particular job

with the example usage sentence:

There are dozens of new companies entering the software market.

which suggests that sentence 1 is correct and sentence 2 is wrong.

But then, according to definition 3c from another dictionary for "enter":

def 3c: to appear for the first time in (something)

with this example usage sentence:

The company has several new products now entering the marketplace.

which suggests that sentence 1 is wrong and sentence 2 is the correct usage. What do native speakers think? Is either 1 or 2 wrong?

Answer 1

There's nothing wrong grammatically with any of the sentences presented by the OP. The verb enter is used in many senses. The OP has described only two meanings of this verb. There are a lot of its uses. The most important and common meaning of the vetb is "to go into a room, building, or other place", which is quite different from the meanings mentioned by the OP. We cannot say that only one meaning is correct and the others are incorrect.
