How many vocabulary in english?

lol..there are many many vocabs..it is also base on words of choice too ..how you speak it.

To start out practicing small , you must choose from 5 to 10 vocabs per day.
must find the definition & find if it is a noun or verb whatsoever.
also make sentences out of the vocabs. say it over 10 times.
read your sentences over and over.
have someone test you.

hopefully that will help :)

5000 ?10000 ? I don't know...

Hello Mike,
Some references state that there are about 500,000 words mounting to 1 million including scientific words. However an average educated person knows about 20,000 words.
You can check this table for further references in detail:

Some methods to increase your vocabulary and memorize them effectively:
- Read texts and books at your level of comprehension and look up new words .List those words in
categories such as office vocabulary , animal life vocabulary , emotions etc.
- Listen to a lot of English through different medias: song lyrics , watch subtitled movies , online
audio material etc.
- Converse with native speakers ,don't hesitate to ask for new words you don't know before.
- Read loud ,record your voice , listen to it and keep repeating the process using each time more
intricate texts with more difficult vocabulary.
- Do any activities that involve using the English language , such as games, quizzes .
- Switch all your operating systems on devices and gadgets to English, so you would be always
reading your instructions in English.
- Make a trip to an English speaking country , visit their museums ,mingle with their people.
Immersing yourself in the culture will be a good motive for you to learn more later.
Good luck:)
