The suffix "-ic" typically means "relating to" or "pertaining to." It is often used to form adjectives from nouns. For example, "historic" means "relating to history," and "poetic" means "relating to poetry."
In your context, the closest definition would be "relating to." If you're looking for a root or other suffixes, "-ic" is indeed a standalone suffix rather than being derived from a root that means "tending toward an action" or "all." If you have specific contexts or examples in mind, I'd be happy to help clarify further!
