What I had learnt in the English lessons in the last week(from 26-11-2007 to 30-11-2007)(3-12-2007)

I had learnt the grammar of adjectives in the last week. Adjectives are words that describe nouns. We can use one or more adjectives before a noun to describe it. We can use nouns as adjectives by putting them before another noun. In general, it's better yo use only one or two adjectives before a noun (with an article, possessive adjective or other determiner if necessary). We usually do not use commas between the adjectives. If we use two adjectives of the same type, we should use and between them. If we use more than two, use commas as well.
