324. Do not confuse the use of in and into. When entrance is denoted use into. As, for example:
- He came into the room.
- He got into the auto.
Often the use of in will give an entirely different meaning to the sentence. For example:
- He ran in the water.
- He ran into the water.
- The man acted as our guide in the city.
- The man acted as our guide into the city.
- The horse ran in the pasture.
- The horse ran into the pasture.
325. Do not use below and under to mean less or fewer in regard to an amount or number. Below and under have reference to place only. It is correct to say:
- He went under the bridge.
- He came out below the falls.
But it is incorrect to say:
- The price is below cost.
- There were under fifty present.
Say instead:
- The price is less than cost.
- There were fewer than fifty present.
