indexed

the word 'indexed' is built upon the noun 'index', which entered english in the late 14th century from latin 'index', meaning 'forefinger, pointer, sign, list'. the latin term itself derives from 'indicare', meaning 'to point out, show', a compound of 'in-' (toward) and 'dicare' (to proclaim). the suffix '-ed' is a native english grammatical marker, used here to form the past tense and past participle of the verb 'to index'. the semantic journey is clear: from the literal idea of pointing with a finger, to the creation of a systematic pointer or list, and finally to the action of creating such a list or the state of being organized by one.

Structure: index + ed index (latin, meaning 'forefinger, sign, list'); ed (old english, suffix forming the past tense and past participle of verbs, or adjectives from nouns/verbs).
