is it? The English wikipedia has an article "Town square"
https://en.wikipedia.org/wiki/Town_square and tries to give a definition
(although the article is in bad shape and also has a warning that the
affirmations are not backed by citations, and it links to articles in other
languages which have different definitions, and which may be partial, due
to these other languages having several similar concepts). Also the article
states that "Other names for *town square* are *civic center
<https://en.wikipedia.org/wiki/Civic_center>*, *city square*, *urban square*,
*market square <https://en.wikipedia.org/wiki/Market_square>*, *public
square*, *piazza <https://en.wikipedia.org/wiki/Piazza>*, *plaza
<https://en.wikipedia.org/wiki/Plaza>*, and *town green*." but these are
not all 1:1 synonymous.

Oxfordlearnersdictionary also has a definition: " [countable] an open area
in a town, usually with four sides, surrounded by buildings"

We did not so far define the words "street" or "road". It is taken as
granted in the highway tag definitions that you know what it is.

whether and how many of all objects with "square" (and similar) in the name
are actually the kind of object we are tagging with place=square will
likely depend on the culture and language. If this works for Italy with all
(or almost) piazza, piazzale, piazzetta, largo, campo, it does not imply it
works in Indonesia as well.

yes, but it implies a certain kind of urbanism, in particular how centers
and peripherical areas look like, and I believe it is not universally
applicable (if it is intended to exclude squares in the outskirts).

no, the place=square can hardly be the same area as a leisure=pitch or
leisure=park. You won't have the park cover the whole area and end at the
buildings, there'll be a way or street along the buildings.

it may depend how you define "street" and "crossed". I guess it includes
pedestrian streets, and crossed may also be seen as "at the borders". If
you read it like this, there won't be many examples that do not fit (can
you post one?).

although not all pedestrian areas are squares. It could also be a parking
(sadly).

I believe it refers to the surface. It the square must not necessarily be a
hardscape.

It may have changed the purpose, but still functionally, architectonically
be a square. I agree with the notion that squares are made to stay, while
streets are made to walk/drive. There mustn't be "events", and many of them
are made to make a building stand out more (e.g. a square in front of a
castle or church).

agreed, it wasn't a good definition before (it did not explain to someone
unfamiliar with the concept, when to apply the tag), but at least it didn't
exclude some kinds of squares by setting criterions that seem not
universally shared.
