not projective; allowing crossing dependencies
Etymology
'non-projectivity' originates from English, formed by the negative prefix 'non-' (meaning 'not') + 'projectivity' (the noun built from 'projective' + suffix '-ity'). 'Projective' ultimately derives from Latin roots related to 'throwing forward'.
'projectivity' was formed in English from 'projective' + the nominalizing suffix '-ity'; 'projective' came via Medieval/Modern Latin 'projectivus' from Latin 'projectus' (past participle of 'proicere'/'proicere' < 'pro-' + 'iacere/jacere'), and the prefix 'non-' was added in English to negate the term, yielding 'non-projectivity'.
Initially derived from Latin notions of 'thrown forward' (literal sense), the element 'project-' shifted to metaphorical senses (e.g., projecting, mapping, structural relation). In modern technical usage, 'projectivity' and thus 'non-projectivity' refer to a formal structural property of syntactic representations rather than a physical action.
Meanings by Part of Speech
Noun 1
the condition or property of a syntactic dependency tree or relation in which one or more dependencies are non-projective — i.e., dependency edges cross when drawn above the sentence's word order.
Non-projectivity occurs in languages with freer word order and is a central concern in dependency grammar and parsing algorithms.
