What does twinning mean?
Twinning has two broad meanings, both built around the idea of two things being closely associated. Most commonly in modern civic and institutional contexts, it refers to the formation of a partnership between two towns, cities, schools, or similar organizations. It can also mean the birth of twins or the act of producing them. As a verb, twinning describes either pairing two comparable entities or giving birth to twins. The word is neutral and common in journalism, administration, education, and family discussion, although the civic sense is especially associated with British usage, while American English often prefers “sister city” or “sister-city partnership.” The term can carry positive connotations of friendship and cooperation, but its literal family sense is occasionally used humorously when events or difficulties happen in pairs. Because it combines a numerical idea with several modern metaphors, twinning remains useful where “pairing” alone might sound too mechanical and “twins” alone would be too narrow.
The practice or result of pairing two similar entities, especially towns, cities, schools, or organizations; also the process of giving birth to twins.
"The twinning of the two cities has led to exchanges in art, education, and public policy."
The institutional sense is especially common in British English. The plural “twinings” is possible but less common than constructions such as “the twinning of the two cities.”
To form or associate two comparable entities as a pair; also, to give birth to twins.
"The two universities are twinning with institutions in different countries."
In the institutional sense, it is often followed by “with.”
The plural is uncommon; “the twinning of” or “the formation of twinings” is often more natural.
"The museum has supported several international twinings."
From a word rooted in the idea of “two,” twinning can describe a birth, a matched pair, or a friendship between entire cities.

Where does twinning come from?
Twinning was formed in English by adding the suffix -ing to twin. Twin comes from Old English twīn and ultimately from a Germanic word whose Indo-European ancestry is associated with the numeral “two.” The related words twain, twice, and two share that ancient numerical ancestry, while the civic sense of twinning is a metaphorical extension of pairing two matching entities.
How twinning is actually used
Neutral but somewhat formal in civic and institutional contexts. The civic sense is especially common in British English, while US usage often favors “sister city” or “sister-city partnership.” In family contexts, “twins” is generally more familiar and flexible.
