uW Translation Notes:

Note 1 topic: grammar-connect-logic-result

ὃ ἑωράκαμεν, καὶ ἀκηκόαμεν, ἀπαγγέλλομεν καὶ ὑμῖν, ἵνα καὶ ὑμεῖς κοινωνίαν ἔχητε μεθ’ ἡμῶν

(Some words not found in SR-GNT: ὅ ἑωράκαμεν καί ἀκηκόαμεν ἀπαγγέλλομεν καί ὑμῖν ἵνα καί ὑμεῖς κοινωνίαν ἔχητε μεθʼ ἡμῶν καί ἡ κοινωνία δέ ἡ ἡμετέρα μετά τοῦ Πατρός καί μετά τοῦ Υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ)

If it would be helpful in your language, you could rearrange the parts of this section. You could move the clause beginning with so that you also to the beginning of the verse, since that clause gives the reason for the action that the rest of the verse describes. As the General Notes to this chapter suggest, it may be helpful to begin a new sentence here. Alternate translation: [So that you also may have fellowship with us, we are declaring to you what we have seen and heard]

Note 2 topic: figures-of-speech / explicit

ὃ ἑωράκαμεν, καὶ ἀκηκόαμεν

(Some words not found in SR-GNT: ὅ ἑωράκαμεν καί ἀκηκόαμεν ἀπαγγέλλομεν καί ὑμῖν ἵνα καί ὑμεῖς κοινωνίαν ἔχητε μεθʼ ἡμῶν καί ἡ κοινωνία δέ ἡ ἡμετέρα μετά τοῦ Πατρός καί μετά τοῦ Υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ)

John is referring implicitly to the way that he and the other eyewitnesses had seen and heard Jesus when he was alive on earth. If it would be helpful in your language, you could include this information, as in the UST. Alternate translation: [what we saw and heard from Jesus when he was alive on earth]

Note 3 topic: figures-of-speech / exclusive

ἑωράκαμεν, καὶ ἀκηκόαμεν, ἀπαγγέλλομεν & ἡμῶν

˱we˲_˓have˒_seen (Some words not found in SR-GNT: ὅ ἑωράκαμεν καί ἀκηκόαμεν ἀπαγγέλλομεν καί ὑμῖν ἵνα καί ὑμεῖς κοινωνίαν ἔχητε μεθʼ ἡμῶν καί ἡ κοινωνία δέ ἡ ἡμετέρα μετά τοῦ Πατρός καί μετά τοῦ Υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ)

John is speaking on behalf of himself and the other eyewitnesses to the earthly life of Jesus, so the pronouns we and us are exclusive.

Note 4 topic: figures-of-speech / abstractnouns

καὶ ὑμεῖς κοινωνίαν ἔχητε μεθ’ ἡμῶν & ἡ κοινωνία & ἡ ἡμετέρα μετὰ τοῦ Πατρὸς, καὶ μετὰ τοῦ Υἱοῦ αὐτοῦ

(Some words not found in SR-GNT: ὅ ἑωράκαμεν καί ἀκηκόαμεν ἀπαγγέλλομεν καί ὑμῖν ἵνα καί ὑμεῖς κοινωνίαν ἔχητε μεθʼ ἡμῶν καί ἡ κοινωνία δέ ἡ ἡμετέρα μετά τοῦ Πατρός καί μετά τοῦ Υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ)

If your language does not use an abstract noun for the idea of fellowship, you could express the same idea in another way. Alternate translation: [so that you could be close friends with us … we are all close friends with God the Father and with his Son]

Note 5 topic: figures-of-speech / exclusive

ἡ κοινωνία & ἡ ἡμετέρα μετὰ

¬the fellowship & ¬the our_‹is› (Some words not found in SR-GNT: ὅ ἑωράκαμεν καί ἀκηκόαμεν ἀπαγγέλλομεν καί ὑμῖν ἵνα καί ὑμεῖς κοινωνίαν ἔχητε μεθʼ ἡμῶν καί ἡ κοινωνία δέ ἡ ἡμετέρα μετά τοῦ Πατρός καί μετά τοῦ Υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ)

The word our here is likely inclusive, since John is writing to fellow believers. So if your language marks that distinction, you should translate the term as inclusive. Even if your language does not mark that distinction, you can indicate in your translation that the term applies both to John and to the people to whom he is writing. Alternate translation: [we are all close friends with]

Note 6 topic: guidelines-sonofgodprinciples

the the (Some words not found in SR-GNT: ὅ ἑωράκαμεν καί ἀκηκόαμεν ἀπαγγέλλομεν καί ὑμῖν ἵνα καί ὑμεῖς κοινωνίαν ἔχητε μεθʼ ἡμῶν καί ἡ κοινωνία δέ ἡ ἡμετέρα μετά τοῦ Πατρός καί μετά τοῦ Υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ)

Father and Son are important titles. Alternate translation: [God the Father … his Son]
