18-letter words that end in on
- call into question — to raise a question or doubt about
- calling convention — (programming) The arrangement of arguments for a procedure or function call. Different programming languages may require arguments to be pushed onto a stack or entered in registers in left-to-right or right-to left order, and either the caller or the callee can be responsible for removing the arguments. The calling convention also determines if a variable number of arguments is allowed.
- cassini's division — the gap that divides Saturn's rings into two parts, discovered by Giovanni Domenico Cassini (1625–1712) in 1675
- causa sine qua non — an indispensable condition; requisite.
- ceiling decoration — a plaster moulding for the centre of a ceiling; other decoration, such as coving
- cellular automaton — (algorithm, parallel) (CA, plural "- automata") A regular spatial lattice of "cells", each of which can have any one of a finite number of states. The state of all cells in the lattice are updated simultaneously and the state of the entire lattice advances in discrete time steps. The state of each cell in the lattice is updated according to a local rule which may depend on the state of the cell and its neighbors at the previous time step. Each cell in a cellular automaton could be considered to be a finite state machine which takes its neighbours' states as input and outputs its own state. The best known example is J.H. Conway's game of Life.

- computer animation — animated film or video that is generated by computers
- concurring opinion — an opinion issued by one or more judges which agrees with the decision reached by the majority of the court, but offers additional or different reasons for reaching that decision
- conditionalization — the derivation from an argument of a conditional statement with the conjunction of the premises as antecedent and the conclusion as consequent. If the argument is valid, conditionalization yields a truth

- de bruijn notation — (language) A variation of lambda notation for specifying functions using numbers instead of names to refer to formal parameters. A reference to a formal parameter is a number which gives the number of lambdas (written as \ here) between the reference and the lambda which binds the parameter. E.g. the function \ f . \ x . f x would be written \ . \ . 1 0. The 0 refers to the innermost lambda, the 1 to the next etc. The chief advantage of this notation is that it avoids the possibility of name capture and removes the need for alpha conversion.
- de-differentiation — a process by which structures or behaviors that were specialized for a specific function lose their specialization and become simplified or generalized.
- de-objectification — to present as an object, especially of sight, touch, or other physical sense; make objective; externalize.
