Synonym discussion
Sense: adjective/1
All four words describe sound quality, but they differ in specificity and connotation. 'Metallic' is the most neutral — it simply means 'like metal' and can describe pleasant guitar tones or harsh screeches. 'Thin' focuses on a lack of fullness or body in the sound; a thin voice may be weak but not necessarily unpleasant. 'Reedy' is more specialised and is used mainly for voices or wind instruments that are high-pitched and slightly nasal. 'Tinny' is the most negative of the group: it always implies poor quality, as if the sound is coming through cheap equipment or thin metal. For example, a vintage radio might produce a 'tinny' version of a jazz recording, while a person's voice is more likely to be described as 'thin' or 'reedy' than 'tinny'.
Etymology
Formed from the noun 'tin' (the metal) plus the adjective-forming suffix '-y' (meaning 'having the quality of'). The sound-related sense appeared in the early 1900s, when early radios and cheap phonographs produced a thin, metallic tone that listeners likened to the sound of tin being struck. The informal noun sense 'a can of beer' developed in Australian English in the mid-20th century, referring to beer sold in tin-plated steel cans.
