The words typical and particular are both adjectives. Typical means something that is of a type. The object it describes is one that belongs to the group, is part of the group, or is a typical example of what you would find in the group.
To be typical is to be of a type, meaning that a person or thing has the same characteristics of everyone or everything else in the group. The word particular, on the other hand, is used to single out a specified group or class. Specific means to insist that something be correct or suitable in every detail, or it is an individual item which possesses a specific quality.
