What does coordinate mean?
A coordinate is most familiarly one of a set of numbers that pinpoints the exact location of a point relative to fixed reference lines, such as the x- and y-axes of a graph or the latitude and longitude of a map. Beyond mathematics, the term also describes a person or thing that is equal in rank or importance to another. As a verb, to coordinate means to arrange different people, parts, or activities so that they function together smoothly and efficiently — a skill prized in project management, event planning, and teamwork of all kinds. The word carries connotations of order, precision, and collaboration: well-coordinated efforts succeed through harmony, while poor coordination leads to chaos and duplication. Derived from Latin roots meaning 'to arrange in order', the word entered English in the seventeenth century and remains indispensable wherever positions must be specified or combined action achieved.
Each of a set of numbers that specifies the position of a point relative to a set of reference lines or axes; also, a person or thing of equal rank or importance with another.
"The pilot reported her position using the coordinates 40.7° N, 74.0° W."
In everyday speech outside mathematics, the plural 'coordinates' is common when referring to a location, e.g. 'send me your coordinates'.
To organize and synchronize the different elements of a complex activity, or the people involved in it, so that they work together effectively.
"She coordinated the volunteers to make sure every station was staffed during the marathon."
Equal in rank, importance, or authority; belonging to the same order or class.
"The two departments have coordinate status within the organization."
The plural is standard when referring to multiple numerical values locating a point or place; 'coordinate' in the singular usually refers to a single value within such a set, or metaphorically to an equal partner.
"Send me the coordinates of the campsite so I can find it on the map."
Every point on every map, graph, and GPS screen you've ever read comes down to a pair of humble numbers called coordinates — invented because a philosopher lay in bed watching a fly walk across the ceiling.

Etymology of coordinate
The word derives from the Latin 'coordinatus', the past participle of 'coordinare', meaning 'to arrange together' or 'set in order', formed from the prefix co- ('together') and ordinare ('to arrange'), which itself stems from 'ordo', meaning 'row' or 'order'. It entered English in the early seventeenth century, initially in logical and grammatical contexts describing elements of equal rank. Its mathematical sense became firmly established after René Descartes developed analytic geometry in the seventeenth century, giving rise to the Cartesian coordinate system. Cognates sharing the same root include 'subordinate', 'inordinate', and 'ordinary'.

Usage notes
The word is fully polysemous across its three parts of speech: the verb sense is common in workplace and organizational contexts, while the mathematical noun dominates academic usage. In British English the spelling is often written with a hyphen ('co-ordinate') or even as 'coördinate' with a diaeresis in older texts, though unhyphenated 'coordinate' now prevails. The verb takes stress on the second syllable (-nate), whereas the noun typically stresses the first syllable (-or-) in careful speech.
Don't confuse with
'Co-ordinate' is simply the older British hyphenated spelling of 'coordinate'; both refer to exactly the same thing.
A corollary is something that follows naturally from a proposition or statement, whereas a coordinate is either a position value on a graph or an equal partner in an arrangement.
