NCERT Book Class 11 English (Hornbill) Writing Skills Ch 4 Essay-writing

4. E ssay- wr it ing
Most of us find it difficult to begin writing. We can make this easier
by thinking about the topic either through brainstorming, that is
with several people in a group giving their ideas as they strike them,
or by putting them down on a sheet of paper as they occur to us.
For example, if the topic is ‘Hobbies’, we can draw a circle and write
‘hobbies’ in it:

Hollies

Then we can put down our thoughts as they come to us in a random
manner as shown below.

Having done that we select the points and expand each into a sentence.
1. Hobbies are free-time activities. Examples are stamp-collecting,
painting etc.
