the word 'wraithlike' is a modern english compound adjective formed from the noun 'wraith' and the adjectival suffix '-like'. the term 'wraith' entered standard english from scots in the early 16th century, its origins shrouded in uncertainty but often linked to old norse concepts of a guardian spirit or old english notions of wrath, both paths leading to an association with an ominous, spectral apparition. the suffix '-like' is a native english element from old english 'līc', originally meaning "body" or "form," which evolved into a productive means of creating descriptive adjectives. thus, 'wraithlike' literally means "having the form or characteristics of a wraith," its logic directly connecting the ancient, elusive idea of a ghost to any entity that appears eerily pale, thin, or insubstantial.
