Fluency is determined by the amount of words and language constructions that you are able to say without interruption. This means that the more words and phrases you know, the better you will perform expressing your ideas.
One problem is that each subject has his/her own unique wording to identify concepts and related facts. For instance, you could speak about your family extensively because you own plenty of information about them.
On the other hand, if someone asks you to talk about something you have limited information about, say, astrophysics, you will find trouble speaking with fluency due to your limitation from that field. The same would happen to the most eloquent speaker, who will not be able to express sentences coherently if not having enough tools to work with.
That means one can only speak confidently and without effort when there is previous background knowledge; therefore, the best way to be fluent is by gathering vocabulary that is appropriate to one’s particular matter. In addition, as we are speakers of English as a second language, we are at disadvantage because we are not exposed to those words at every moment.
Consequently, we have to invest time to compensate this deficiency, by memorizing new words and supplementary vocabulary. This guarantees our readiness to handle diverse areas with correct fluency. The following are suggestions of vocabulary to research and use at initial levels:
- Vocabulary related to everyday activities. How we live, work, entertain and interact with others.
- Vocabulary related to our profession, concepts, theories or knowledge learned in college or connected to our occupations. Everything that you do and say in your native language has specific wording or phrasing in English. Find it and use it every time you can.
- Additional vocabulary. This relates to the topics you are personally interested in. In your native language, there are many words or phrases that do not translate literally. You will have to look up a language structure to help you be better understood.
