Ac`ci*den"tal, a. Etym: [Cf. F. accidentel, earlier accidental.]

Syn.
– Casual; fortuitous; contingent; occasional; adventitious.
– Accidental, Incidental, Casual, Fortuitous, Contingent. We speak
of a thing as accidental when it falls out as by chance, and not in
the regular course of things; as, an accidental meeting, an
accidental advantage, etc. We call a thing incidental when it falls,
as it were, into some regular course of things, but is secondary, and
forms no essential part thereof; as, an incremental remark, an
incidental evil, an incidental benefit. We speak of a thing as
casual, when it falls out or happens, as it were, by mere chance,
without being prearranged or premeditated; as, a casual remark or
encounter; a casual observer. An idea of the unimportant is attached
to what is casual. Fortuitous is applied to what occurs without any
known cause, and in opposition to what has been foreseen; as, a
fortuitous concourse of atoms. We call a thing contingent when it is
such that, considered in itself, it may or may not happen, but is
dependent for its existence on something else; as, the time of my
coming will be contingent on intelligence yet to be received.
