small amount left behind
A small part or thin layer that is left after most of something is gone, used, or cleaned away.
Schéma d’usage :
the residue of [something]
Erreur fréquente :
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.
Synonymes
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.)
Antonymes
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.
Schéma d’usage :
the residue of [someone]’s estate
Erreur fréquente :
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.
Synonymes
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.)
Antonymes
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.
Schéma d’usage :
[amino acid] residue in [a protein]
Erreur fréquente :
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.
Synonymes
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'.)
Antonymes
molecule (Refers to the complete structure made of many residues or units, in contrast to a single residue.)

|tyrosine residue

Exemples
- The serine residue in the active site is essential for the enzyme’s function.
- Phosphorylation of this tyrosine residue triggers a signaling cascade in the cell.
- Each amino acid residue in the protein is numbered according to its position in the sequence.
- The side chain of the lysine residue forms a salt bridge with a neighboring group.
Exemples pédagogiques
- Each amino acid residue has a different side chain.
- This protein has a histidine residue at position ten.
- The enzyme changes when one residue is replaced by another.

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.
Schéma d’usage :
the residue of [number] modulo [number]
Erreur fréquente :
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.
Synonymes
remainder (Used for what is left after one integer is divided by another; overlaps in modular arithmetic, but 'residue' is more formal and structural.)
Antonymes
multiple (A number that divides exactly with no remainder or residue, opposing the idea of having something left over.)

- Each residue class contains all integers that leave the same remainder when divided by n.
Exemples pédagogiques
