1. To furnish with strength or means for the successful performance of any action or the attainment of any object; to aid; to assist; as, to help a man in his work; to help one to remember; — the following infinitive is commonly used without to; as, "Help me scale yon balcony." Longfellow.

3. To furnish with relief, as in pain or disease; to be of avail against; — sometimes with of before a word designating the pain or disease, and sometimes having such a word for the direct object. "To help him of his blindness." in is used for that function; — "to help him in his misery" Shak. The true calamus helps coughs. Gerarde.
4. To change for the better; to remedy. Cease to lament for what thou canst not help. Shak.

"A man is well holp up that trusts toyou." Shak.
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 coöperation 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.
