lengthy

The word 'lengthy' is a relatively modern English formation, first appearing in the late 17th century. It is built upon the native English noun 'length', which itself evolved from the Old English 'lengþu', a derivative of the Proto-Germanic adjective 'langaz' (long). The addition of the productive adjectival suffix '-y' (from Old English '-ig') directly creates the meaning "having the quality of length." While 'long' is the primary adjective, 'lengthy' often carries a connotation of excessive or tedious duration, particularly when applied to speeches, processes, or documents, thus adding a nuanced layer of meaning to its straightforward morphological construction.

Structure: length (noun) + y (adjective-forming suffix) 'length' is from Old English 'lengþu', a noun derived from the adjective 'lang' (long) with the abstract noun suffix '-þu' (similar to '-th'). 'y' is an English adjective-forming suffix of Germanic origin, used to form adjectives meaning "characterized by" or "full of."
