Abstruse, adj. difficult to understand, hidden. It should not be misused for abstract.
1) Metaphysics. Something whose essence requires naturally that it exist in another being; a being or a being; a mere modification or attribute of another being; being in a qualified sense; being inhering in another being as in a subject of existence; one of the nine modes in which substance is determined in its being; ens entis. In the plural, accidents are often referred to as appearances, phenomena, or species.
- Absolute Accident,
- one that is really distinct from the subject in which is inheres, as opposed to a modal accident.
- one that immediately affects the substance to which is belongs as opposed to a modal accident that immediately affects another accident; thus, quantity as distinguished from shape.
- Intrinsic accident, one that really modifies a subject, and so is not merely an extrinsic change or name; an accidental form.
- Metaphysical accident, any accident in the nine categories of accidental being.
- Modal accident,
- a state affecting the substance, but which is thought of by some scholastic philosophers as not really distinct from the substance or other accidents in the being; e.g., sitting, standing.
- one that immediately inheres in or affects other accidents.
- a mode of being. See MODE.

2) Causal sense. What is unforeseen or unintended; the result of chance.

4) Logic. An attribute belonging to some nature but not constituting its essence or a part of its essence. It is sometimes called a logical accident.
- Contingent (logical) accident, an attribute that is not characteristic of or essential to a nature, but may be present or absent in different members of the same species; e.g., white color in human skin.
- Proper accident, a characteristic or distinctive accident essentially belonging to or necessarily resulting from some essence, and so found in all members of the species; a propery or proprium. See PREDICABLE
