Etymology of CROSSNUMBER

The term "crossnumber" is derived from the combination of two words: "crossword" and "number".

The word "crossword" was first recorded in the Oxford English Dictionary in 1920. It refers to a word puzzle or game that involves filling in white squares with letters to form intersecting words, based on given clues. The "cross" in "crossword" indicates the intersecting nature of the words.

The term "number" simply refers to numerical digits or figures.

Therefore, when the concept of a crossword puzzle was applied to numbers, combining the intersecting nature of words with numerical clues, the term "crossnumber" emerged. It specifically represents a puzzle or game that offers a grid of empty squares to be filled with numerical digits, forming intersecting equations or problems based on given clues.
