small amount left behind
A small part or thin layer that is left after most of something is gone, used, or cleaned away.
用法パターン：
the residue of [something]
よくある間違い：
Learners sometimes use 'leftover' instead of 'residue' in scientific or cleaning contexts. 'Leftover' is common for food or general items, while 'residue' is more natural for thin layers or small amounts of substances on a surface or remaining after a process.
類義語
remnant (Very close in meaning; often used for what is left over, but can sound slightly more literary or general than the more physical-sounding 'residue'.)
|
deposit (Suggests a layer that has built up on a surface, often over time; usually more obviously physical than 'residue'.)
|
trace (Emphasizes that only a very small, often barely noticeable, amount remains.)
対義語
entirety (Focuses on having the whole of something, with nothing removed or left over.)
|
bulk (Highlights the main or larger part of a substance, as opposed to the small part that remains as residue.)

remainder of an estate
The money and property that are left from a dead person’s estate after paying debts, taxes, and special gifts named in the will.
用法パターン：
the residue of [someone]’s estate
よくある間違い：
Learners may think 'residue' here means a physical layer or dirt. In legal contexts, it is an abstract financial term for the remaining part of an estate after all specific payments.
類義語
remainder (A general word for what is left; in legal writing it is often used in a similar way, but 'residue' is the more precise legal term for the final balance of an estate.)
|
residuary estate (A technical legal phrase that refers specifically to the residue as defined in a will.)
対義語
bequest (Refers to a specific item or sum of money left to someone in a will, as opposed to the leftover estate that forms the residue.)

part of a larger molecule
In chemistry and biology, one small unit, such as an amino acid, that is joined together with others to make a bigger molecule.
用法パターン：
[amino acid] residue in [a protein]
よくある間違い：
Learners sometimes confuse this technical meaning with the everyday idea of dirt or a thin layer left on a surface. In biochemistry, a 'residue' is a structural unit, not something left over or dirty.
類義語
unit (A very general word for one part of something larger; less precise than the technical term 'residue'.)
|
moiety (A technical term used in chemistry for a distinct part of a molecule; similar but not identical in use to 'residue'.)
対義語
molecule (Refers to the complete structure made of many residues or units, in contrast to a single residue.)

mathematical remainder or value
In mathematics, a number or value that shows what is left when you divide by another number, or a special value used in some advanced areas like complex analysis.
用法パターン：
the residue of [number] modulo [number]
よくある間違い：
Learners may think 'residue' in math is always exactly the same as a simple remainder. In higher mathematics, it can have a more specialized meaning, such as a value linked to a singularity in complex analysis.
類義語
remainder (Used for what is left after one integer is divided by another; overlaps in modular arithmetic, but 'residue' is more formal and structural.)
対義語
multiple (A number that divides exactly with no remainder or residue, opposing the idea of having something left over.)
