Shades of meaning
Faint, with the general sense of lacking strength or effectiveness, covers a wide range of meaning, signifying overcome with physical weakness or exhaustion, or lacking in purpose, courage, or energy, as said of persons; or lacking definiteness or distinctness of color or sound, as said of written characters, voices, or musical notes. A person may be faint when physically wearied, or when overcome with fear; he may be a faint adherent because naturally feeble or purposeless, or because half-hearted in the cause; he may be a faltering supporter because naturally irresolute or because faint-hearted and timid in view of perils that threaten, a listless worker, through want of mental energy and purpose. Written characters may be faint or dim, either because originally written with poor ink, or because they have become faded by time and exposure.
