    • n superposition In botany, same as anteposition, 2.
    • n superposition Specifically, in geology, noting the relations of stratified formations to one another from the point of view of the relative time of their deposition. That underlying beds are older than those which cover them is called the law of superposition. The apparent exceptions to this law are those instances in which stratified masses have been so disturbed and overturned since their deposition that older beds have been made to rest upon newer ones.
    • n superposition In geometry, the ideal operation of carrying one magnitude to the space occupied by another, and showing that they can be made to coincide throughout their whole extent. This is the method of Euclid, to which his axiom, that things which coincide are equal, refers; but the use of the word superpose in this sense appears to be due to Auguste Comte (French superposer).
    • n superposition In the early church, an addition to or extension of a fast; a fast longer than the ordinary fast.
