mood

=Mood:= In linguistics, many grammars have the concept of **grammatical mood**, which describes the relationship of a verb with reality and intent.

Shifts in Mood:
//Your room needs to be cleaned.// //Clean your room.// //If I were going to clean my room, I would have done it already.// //Next, I will explain how to format a disk. First, insert the disk into the disk drive.//
 * A shift in mood refers to a shift in the approach to a topic. In the **indicative** mood, ideas are expressed in a matter-of-fact way.
 * The **imperative** mood is characterized by commands or requests.
 * The **subjunctive** mood refers to wishes or statements contrary to fact.
 * Avoid abrupt shifts from statements to commands. If a shift is necessary, signal the change to your readers.
 * The writer of the above sentences prepares readers for a shift in the way the topic will be approached.

ex.-//The directions suggest first laying out and identifying all the parts. Next, apply the first coat.// revised ex.-//The directions suggest first laying out and identifying all the parts. The next step is to apply the first coat.//
 * Since the writer intends to explain the steps in painting, not to give direct commands, the writer has shifted from the imperative to the indicative mood.
