The term 'Feature of Most Crosswords' can be broken down into two crossword solutions: THEME (5 letters) and SYMMETRY (8 letters). The THEME of a crossword is the subject or topic that all of the clues and answers relate to. SYMMETRY is the arrangement of words in a crossword puzzle so that the same pattern is repeated across the grid. This means that the same words, phrases, or clues are placed in the same positions on both sides of the grid. Both of these elements are important features of most crosswords.
