Indirect Speech (also referred to as 'reported speech') refers to a sentence reporting what someone has said. It is almost always used in spoken English.

If the reporting verb (i.e. said) is in the past, the reported clause will be in a past form. This form is usually one step back into the past from the original.

For example:

• He said the test was difficult.
• She said she watched TV every day.
• Jack said he came to school every day.

When we use reported speech, we are usually talking about the past. So verbs usually change to the past in reported speech.
For example:

am/is -> was                have/has -> had                  are -> were
will -> would can -> could

if you know who you are talking to, use tell:
Joe told me that he liked Jane. (Not Joe said me...)

use say for other situation:
Joe said that he liked Jane. (Not Joe told that he...)
