charismatic
having great charm or appeal
And now for some Greek: The secular and religious senses of charismatic both come from the Greek charis, meaning "grace."
compassionate
feeling or showing concern for someone who is sick, hurt, poor, etc.
The original meaning of "passion" referred to the sufferings of Jesus ("the Passion of Christ"), and compassionate once meant "calling forth pity." Nowadays, compassionate implies tenderness and understanding, and a desire to aid and spare another.

intrepid
feeling no fear; very bold or brave
Intrepid shares an ancestor with trepidation (from the Latin word trepidare, "to tremble") – but the in- prefix negates the trembling and fear (love those prefixes - Ms.B!)
magnanimous

and here's the Latin! A magnanimous person shows great spirit, and the word itself refers to those qualities: magnanimous comes from the Latin magnus, "great" + animus, "spirit."

And it comes from: the days of Middle English and has its origins in a Latin word meaning "to be strong."
