Some English words are made up of the same part and have different beginnings and different endings, such as import, export, report and transport. All these words, you can see, have the same port, which come from the Latin word, meaning to carry or to move from one place to another. And according to the bit at the beginning, which we call the prefix the meaning changes. Import means to carry in or to bring into a country, export, ex means out of, so this word means to carry out of the country, re means back, so the report means to tell somebody, to bring back information to somebody, transport, trans means across and it means to carry across one place to another.
Let's look at the following words: supporter, reporter, importer and exporter. You can see that in this case these words are nouns which are made up of the verbs plus a suffix, thus meaning a person who completes the verb. So supporter means somebody who supports. A reporter is somebody who reports. Importer is somebody who imports and exporter is somebody who exports, and so on.
