How to start learing grammar:

Many people do not find it easy to start learning English grammar. they are always inquiring about what kind of grammar lessons to start with.
Yes, this is in fact a little bit problematic unless the learner does not have some mastery of the language. But, this does not mean that there is no chance for a beginner to start approching English grammar. Beginners do equally have the same opportunities to start learning Grammar and to upgrade during the process.
From my own experience as a University English student, I would recommend beginners to start with tenses. Tenses are a good start for beginners. thanks to being exposed to different tenses, the learner would little by little devolep some awareness of the different english tenses.

Afterwards, the learner should move on to learning the differnt kinds of articles (definite and indefinite). Articles would make it easier to overcome the confusion that happens between countable, uncountable and abstract nouns. Don't get shoked if you still don't figure out the difference between them. By the time you understand how and when to use articles, you'll have been fully aware of the distinction between countable, uncountable and abstract nouns.

The third grammar lesson to tackle would be "Prepositions". Prepositions are so many in English, you cannot limit then to only one list. Nevertheless, there is a limited number of prepositions that are frequently used, and that need to be understood and put into practise through different exercices you can find abundantly available on the Net.
The fourth lesson to take would be concerned with relative pronouns. There are only eight relative pronouns in English (who, whom, which, that, whose, what, when, where)which make it easier for you to learn by heart.

Finally, after having fully understood and put into pracise the preceding four lessons, it is recommended to start up with nouns, adjectives, adverbs and verbs, and figuring out the distinction between them. This last lesson would be a little bit challenging and time consuming, so be patient.
