'nonspiderlike' originates from Modern English, specifically formed by the negative prefix 'non-' (from Latin 'non' meaning 'not'), the noun 'spider' (from Old English 'spithra' meaning 'spinner'), and the suffix '-like' (from Old English '-lic' meaning 'having the form of').

'spider' changed from Old English 'spithra' to Middle English 'spidre' and eventually became the modern English 'spider'; the suffix '-lic' evolved into the Modern English '-like'; the prefix 'non-' was borrowed into English from Latin in Medieval/Modern English and combined with these elements to form compounds like 'nonspiderlike'.

Initially, the parts meant 'not' + 'spinner' + 'having the form of'; together they originally indicated 'not having the form or qualities of a spider,' and the modern meaning remains essentially the same.
