Can't find a word to fit those letters .... What is the clue

[coyn]

Unific would fit the letters and spaces but saying what the clue is usually helps

[gadfly]

Thanks to coyn and kosoro. Clue is ' Having the power or means to bring together for a common purpose' Thought of unific, but its not in my dictionary.

[double-blade]

it is unific
