I take a function phrase. The definition is up to you eg. List
a = {cat, E, in, the, hat, E, okay, fine, E};
Select[c = phrase[];
FoldList[If[#2 =!= E, Append[#1, #2], c = phrase[]] &, c, a
# =!= phrase[] &]
{phrase[cat], phrase[in], phrase[in, the], phrase[in, the, hat],
phrase[okay], phrase[okay, fine]}
