Almsgiving, n.
The giving of alms.
Shades of meaning
Fernald has no entry of its own for almsgiving; he lists it under benevolence.
Where he writes about it:
Charity, which originally meant the purest love for God and man (as in 1 Cor. xiii), is now almost universally applied to some form of almsgiving, and is much more limited in meaning than benevolence. — from benevolence
