OET interlinear YHN (JHN) 16:21

uW Translation Notes:

Note 1 topic: figures-of-speech / genericnoun

ἡ γυνὴ ὅταν τίκτῃ, λύπην ἔχει, ὅτι ἦλθεν ἡ ὥρα αὐτῆς; ὅταν δὲ γεννήσῃ τὸ παιδίον, οὐκέτι μνημονεύει τῆς θλίψεως διὰ τὴν χαρὰν, ὅτι ἐγεννήθη ἄνθρωπος εἰς τὸν κόσμον

the woman whenever ˱she˲_/may_be/_bearing sorrow /is/_having because came the hour ˱of˲_her whenever but ˱she˲_/may/_bear the little_child no_longer ˱she˲_/is/_remembering ˱about˲_the tribulation because_of the joy that /was/_born /a/_person into the world

Jesus is speaking of women in general, not of one particular woman. If this would be misunderstood in your language, you could use a more natural expression. Alternate translation: “When women give birth, they have pain because their hour has come, but when they have given birth to their children, they no longer remember their suffering, because of the joy that men have been born into the world”

Note 2 topic: figures-of-speech / metonymy

ἡ ὥρα αὐτῆς

the the hour ˱of˲_her

Here, her hour refers to the time when the woman gives birth. If it would be helpful in your language, you could express the meaning plainly. Alternate translation: “the time for her to give birth”

Note 3 topic: figures-of-speech / abstractnouns

οὐκέτι μνημονεύει τῆς θλίψεως

no_longer ˱she˲_/is/_remembering ˱about˲_the tribulation

If your language does not use an abstract noun for the idea of suffering, you could express the same idea in another way. Alternate translation: “she no longer remembers that she suffered”
