Here are two words which we use especially in nigeria and most times we mix them up in their usage.
1) Offload
2) Unload.
You will hear someone say: I Offload the shipment of goods.
In correct English it's incorrect. Rather you use UNLOAD when it comes to goods and things.
Eg. Unload that vehicle
The boxes were unloaded.
To OFFLOAD is to get rid of something, or people.
For instance, a coach may offload a player who's not performing.
You can offload a car by selling it out maybe because it's no longer fit for use.
Hope we learned something today.
Cheers.
