I am wondering if it is correct to use continual or continually in the following sentence.

I am grateful for our continual unfolding journey.

Thank you for your advice... ~ Pia ~ :)

I would use the adverb form 'continually,' as it appears to be modifying 'unfolding,' which is being used as an adjective to modify the noun 'journey.'

'Continual' would be used if it were directly modifying the noun.
