A command is a statement requesting somthing to be done. Examples of a command are "Read." and "Write." Since comands are always directed towards someone, it is optional to include the person's name (or a pronoun) before the command.

respect / non-respect

In Thamil, commands have 2 forms. The first form (which is just the verb root) is the non-respect form. This form is given to people of the same age or people younger. As previously said, a verb root by itself can be used as a command without respect. The other form of commands are those given with respect.

commands with respect
verb root + உங்கள்

Forming commands with respect uses the usual rules for adding suffixes.
