G5605–ὠδίνω–ōdinō

you for whom I am again, as it were, undergoing the pains of childbirth, until Christ is fully formed within you.

ὠδίνω ōdinō “I travail”

For it is written, "Rejoice, thou barren woman that bearest not, break forth into a joyful cry, thou that dost not travail with child. For the desolate woman has many children--more indeed than she who has the husband."

ὠδίνουσα, ōdinousa “travailing,”

and she was crying out in the pains and agony of childbirth.

ὠδίνουσα ōdinousa “being in travail”
