“appertain” in Latin

The English word appertain itself goes back to Latin pertineō, through appertinēre.

Riddle & Arnold A Copious and Critical English–Latin Lexicon, 1864

appertain
belong; of strict possession; est aliquid alicujus (not alicui): aliquis possidet aliquid. This appertains to me, hic meus est. [So always the possessive pronoun, not the dative of the personal one.]
Belong, relate to, etc., pertinere ad aliquid: spectare ad aliquid: referri or referendum esse ad aliquid. It appertains to a happy life, ad beatam vitam pertinet. Often by esse with the genitive.
To be due to, deberi.
