this is definitely a word that the mainstream dictionary forgot!
to be uplifted by a new idea/situation
to be in the process of a new idea eg i am revelating
to be speaking of having a revelation in past tense eg i had a revelating day yesterday
i found that the dogging in Doncaster was quite revelating
I had a 'revelating' day..meaning i had day that gave me a whole new perspective on things!!
