slangy

the word 'slangy' is a modern english formation, directly derived from the noun 'slang' with the addition of the productive adjectival suffix '-y'. the noun 'slang' itself has obscure origins, first appearing in the mid-18th century; it is possibly related to the verb 'sling', suggesting language that is "slung" or thrown about casually, or it may have roots in scandinavian languages. the suffix '-y' is an ancient and versatile formative element, traceable through old english and proto-germanic back to a proto-indo-european adjectival suffix. thus, 'slangy' logically constructs its meaning as "having the qualities of slang," evolving from the literal action of slinging words to describing a style of speech characterized by informal, trendy, or unconventional vocabulary.
