Xmas Spectator

2A, 118, 1 and 19 (three of five words and one of three, ignore two apostrophes) are of a kind. The first word of a further example sounds like what is defined by both 53 and 8/92; 39, 72 and 110 may each precede its second word; its third is associated with 75, 95/54D and 97; 37, 52A, 4, 43, 47D, 68, 74 and 107 are its fourth; its fifth is part of 57, 77 and 99; ‘34/62/35’ defines an anagram of its sixth; and its seventh capitalised is an abbreviation of the 6/91D. Its sixth word will appear diagonally in the grid and must be shaded.
