him,he;the third-person masculine singular personal pronoun used after a preposition,or as the predicate of a linking verb,or when disjoined from a sentence,or as a stressed subject
1 The disjunctive (tonic) forms are also used after an explicit preposition (de/d’,à,pour,chez,dans,vers,sur,sous, ...), instead the accusative, dative, genitive, locative, or reflexive forms, where a preposition is implied. 2Il is also used as an impersonal nominative-only pronoun. 3On can also function as a first person plural (although agreeing with third person singular verb forms). 4 The nominal indeterminate formce (demonstrative) can also be used with the auxiliary verbêtre as a plural, instead of the proximal or distal gendered forms. 5 The reflexive third person singular forms (se ors’) for accusative or dative are also used as third person plural reflexive. 6Vous is also used as the polite singular form, in which case the plural disjunctive tonicvous-mêmes becomes singularvous-même. 7Ils,eux andeux-mêmes are also used when a group has a mixture of masculine and feminine members.
Third person pronominal forms used as formal terms of address to refer to second person subjects (with the first letter frequently capitalised as a sign of respect, and to distinguish them from third person subjects). Unlike the singular forms, the plural forms are mostly antiquated terms of formal address in the modern language, and second person plural pronouns are almost always used instead.

Also used as indefinite pronoun meaning “one”, and to form the passive.
"lui", in Charles du Fresne du Cange’sGlossarium Mediæ et Infimæ Latinitatis (augmented edition with additions by D. P. Carpenterius, Adelungius and others, edited by Léopold Favre, 1883–1887)
Whereas singular masculine proper names always form the genitive and dative using the preposedlui, feminine ones only do so when the specific name doesn't have a genitive/dative form itself:casa lui Carmen butcasaMariei. This rule is ignored by many in informal situations andlui is used with feminine names either way.
