In plain English: Particularly means especially or more than anything else.

Usage: Use particularly to specify something that stands out more than others within a group or situation. Place it directly before the word you are emphasizing to highlight its special significance.
The word particularly comes from combining the adjective particular with the suffix -ly to form an adverb. It entered English by simply adding a common grammatical ending to indicate that something is done in a specific or distinct manner.
