Hang, suspend, sling, dangle mean to place or be placed so as to be supported at one point or on one side, usually a point or side at the top.
Hang typically implies a fastening to an elevated point or line so as to allow motion to what falls from such a point or line.
In extended use hang often implies a position or a relation suggestive of hanging, such as that of something poised or seemingly poised in the air or of one thing dependent upon another or of something clinging or adhering to something else.
Suspend is preferred to hang (or hung ) when support from a point above suggests flexibility, free motion or movement, or a display of skill.
Suspend is also employed more often than hang when a floating in a fluid (as air or water) is suggested (see SUSPENDED ).
Sling basically implies the use of a sling for hoisting or lowering heavy or bulky articles with ease. Sometimes the term implies a hanging over the shoulder, or arm, or similar support (as for ease in carrying) <slung a basket on her arm> <sling a scaffold from a roof>
Dangle implies a hanging loosely in such a manner as to swing or sway or twist to and fro.
In extended use dangle usually implies dependence on someone, often a loose dependence or connection, in hope of a reward for attentions or services.
