Shades of meaning
Fernald has no entry of its own for indecision; he lists it under doubt.
Where he writes about it:
Misgiving is ordinarily in regard to the outcome of something already done or decided; hesitation, indecision, and irresolution have reference to something that remains to be decided or done, and are due oftener to infirmity of will than to lack of knowledge. — from doubt
