Many words in English are based on the same root words, and knowing what these mean can help us with spellings.

The root word 'port' comes from two similar Latin words meaning 'to carry' and 'gateway'.

for example:

A porter is a person who carries people's luggage at a railway station or hotel.

A port is a place where ships leave one country for another, so it is a kind of gateway.

The word is also linked to carrying things, as ports take people and products from one place to another.
