The act or process of linking things together; the state of being linked or connected.
From 'enlink' plus the suffix '-ment,' which transforms verbs into abstract nouns representing the result or process of an action. This pattern appears in many English words like 'employment' and 'engagement.'
The '-ment' suffix was hugely popular in Middle and Early Modern English for creating sophisticated nouns that made ordinary actions sound more formal and important—'enlinkment' sounds grander than just 'linking,' which is probably why fancy writers used it.
