Syn. -- To aid; assist; succor; relieve; serve; support; sustain; befriend. -- To Help, Aid, Assist. These words all agree in the idea of affording relief or support to a person under difficulties. Help turns attention especially to the source of relief. If I fall into a pit, I call for help; and he who helps me out does it by an act of his own. Aid turns attention to the other side, and supposes coˆperation on the part of him who is relieved; as, he aided me in getting out of the pit; I got out by the aid of a ladder which he brought. Assist has a primary reference to relief afforded by a person who "stands by" in order to relieve. It denotes both help and aid. Thus, we say of a person who is weak, I assisted him upstairs, or, he mounted the stairs by my assistance. When help is used as a noun, it points less distinctively and exclusively to the source of relief, or, in other words, agrees more closely with aid. Thus we say, I got out of a pit by the help of my friend.
