Parsing 19, I’ve assumed that the first two letters are a strange synonym of “for” reversed then the next three a synonym of “dawn on”as a verb then the usual abbreviation for island.

"Hi Pauly, 20 is a three letter word for date inside a three letter word for dress (more usually it’s a plural)
My middle 3 letters would be an abbr for a type of scan - date???
