MEANING: noun: A moving object striking against a stationary object.

ETYMOLOGY: From Latin allidere (to strike against), from ad- (toward) + laedere (to harm). Earliest documented use: 1615 (collision is also from 1615).

NOTES: In maritime usage, the term allision is used for a vessel striking a fixed object, while collision is between two moving ships. Frequently, the word collision is used in both cases.

WALLISION - to hit the wall

ALLISIN - the ultimate triumph of evil

ALLISON - Noah's comment just before he set sail in the Ark
