transitorily

hetkellisesti puhekieltä In a transitory way.
1819, Henry Home Kames, Elements of Criticism, p. 147:

All parts of the experienced world are experienced transitorily. They appear and disappear.

Most transitorily poor households are substantially better off than chronically poor households.

It is not a permanent space: it transitorily colonizes public urban space, overlapping and somehow replacing it.
