What does glassing mean?
Glassing usually means putting glass into or onto something. In construction and manufacturing, it refers to fitting panes or sheets of glass into frames, doors, cabinets, or other structures, and it can function either as a verb, as in “The team is glassing the doors,” or as a gerund or noun, as in “the glassing of the windows.” The word also has a sharply different, chiefly British informal meaning: striking someone with a drinking glass or broken glass, usually in the face, often as an act of intimidation. Context generally makes the intended sense clear, since trade discussions imply glazing while references to an assault imply the violent sense. “Glazing” is usually the more neutral everyday term, whereas “glassing” is especially associated with specialist work but is also conspicuous in news and social discussion when violence involving a glass is meant. The word derives from “glass” and is related to forms such as “glaze” and “glazier.”
To fit, install, or cover something with glass. In chiefly British informal use, it can also mean to strike someone with a drinking glass or broken glass, especially in the face.
"They are glassing the display cabinet before the shop opens."
The violent sense is informal and chiefly British.
The process or work of fitting or covering something with glass; more narrowly, an act of striking someone with a drinking glass or broken glass.
"The glassing of the windows gave the porch an unexpectedly modern appearance."
The craft sense is normally uncountable, while the chiefly British informal sense can refer to individual incidents.
Normally uncountable for the process of fitting glass; “glassings” is the regular plural for separate violent incidents but is uncommon.
"The recording appeared to show two separate glassings outside the venue."
From fitting a window to smashing a glass across a face, “glassing” packs two startlingly different meanings into one word.

Where does glassing come from?
Glassing is formed from glass with the gerund suffix -ing and can therefore name an ongoing action or, when used nominally, the process itself. English glass was inherited through Old English glæs from Proto-Germanic *glāz; its deeper Indo-European ancestry is uncertain, so a more exact derivation would be unsafe. The related form glaze developed through English and French intermediaries, while glazier reflects the same long-established glassmaking and glazing vocabulary.
