Ability
Can someone do it?
modal verb
معنا
Ability tells us what someone can do, whether learned or not. It covers learned skills as well as what someone's body or mind allows them to do. Languages express it with helper verbs, endings, or ordinary phrases, and some have no special form for it. Unlike Permission, Ability concerns what someone can do, not what they are allowed to do.
