To cross or intersect in a pattern, as in 'criss-cross'; can also refer to a short crossing movement.
A reduplication of 'cross,' likely influenced by the pattern it creates. First appeared in English around the 17th century as an intensified or playful version of 'cross,' and 'criss-cross' became the standard form.
Languages love reduplication—repeating words or sounds to make them more fun and expressive. 'Criss-cross' is way more satisfying to say than just 'cross,' which is why kids chant it and why your phone's autocorrect recognizes it as a single concept!
