The letter “H” frequently appears as the solution to crossword clues referencing the pronoun “who” when the puzzle requires a single letter answer. This relies on the common phrasing found in questions like “Who is this?” often shortened colloquially to “Who’s this?” The apostrophe represents the elided letter, making “H” the correct response.
This seemingly simple puzzle element highlights the interplay between language, abbreviations, and the deductive reasoning required for solving crosswords. It demonstrates how crossword puzzles can test knowledge beyond simple vocabulary and delve into an understanding of grammatical contractions and informal speech. This type of clue reinforces the importance of considering different interpretations of phrasing and emphasizes the value of lateral thinking.
