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.

The Greek that is transliterated “Cephas” in English — and is an alternative name for Peter — is transliterated in Chinese Protestant translations as jīfǎ (traditional Chinese: 磯法, simplified Chinese: 矶法). The first character jī (磯 / 矶) is not only chosen because of its sound but also because of its meaning: “rock,” corresponding to the meaning of the Aramaic kēp̄ā (כֵּיפָא), to which the Greek Kēphâs (Κηφᾶς) refers and also alluding to Jesus’ proclamation in Matthew 16:18 (see Peter – rock).
Note that Catholic Chinese versions don’t follow the English pronunciation of “Cephas” with its opening [s] sound. They use kēfǎ (刻法) transliterating the [k] sound from the Aramaic and Greek. Kēfǎ does not carry the additional meaning of “rock.” (Source: Jost Zetzsche)

The passage in John 1:42 (“You are to be called Cephas (which is translated Peter)” in English) is solved by various translations like this: “‘I am going to name you Cephas.’ Cephas means ‘Peter.’ Both mean ‘rock.'” (Ojitlán Chinantec), “I am naming you Cephas. ‘Cephas’ in the Jews’ language, ‘Peter’ in the Greek language, the meaning being ‘stone’.” (Alekano), “You will become known as Cephas,’ he said, which in our language means ‘rock.'” (Chol), or “You will be called Cephas and also Peter.” Tenango Otomi.
