The term 'TEARS SHED' can be solved by the four-letter word 'WEEP'. Weeping is a natural response to emotions such as sadness, grief, or joy. It is a form of nonverbal communication that can be used to express a range of feelings. Tears are produced by the lacrimal glands and are composed of water, oils, and proteins. They are released when the body experiences strong emotions, and can be a sign of distress or sorrow.
