For-vað

As defined by the Cleasby & Vigfusson Old Norse to English dictionary:

for-vað

n. shoal water between the cliffs and the flowing tide: hence the phrase, í síðustu forvöð, to pass the last shoal water before the tide cuts the passage off, also metaph. to delay till the last moment; göra flekann allan, ok halda upp forvöðunum þar í hjá, D. n. vi. 167, where it seems to mean a ford.
