Peter - rock

The word pun that Jesus makes in Matthew 16:18 in Greek (using similar words for “Peter and “rock”: πετρος and πετρα) is lost in most languages (such as in English) but is naturally preserved in some languages, such as French (Pierre and pierre), Portuguese (Pedro and pedra), Italian (Pietro and pietra), Latin (Petrus and petram), Modern Greek (Πέτρος and πέτρα), and — to a lesser degree — in Spanish (Pedro and piedra) and in Romanian (Petru and piatră).

Like the Peshitta translation in Syriac Aramaic (Classical Syriac) with the term ܟܹܐܦܵܐ (kēpā), the Neo-Aramaic languages of Assyrian and Chaldean use terms for both “Peter” and “rock” (and “Cephas”) that are identical (ܟܹܐܦܵܐ and كِيپَا, both pronounced kēpā) so the word pun is preserved in those translations as well.
