throughpenetrating

Throughpenetrating is an adjective used to describe something that penetrates completely through an object, from one boundary to the opposite boundary. The form is uncommon in standard English; more common variants include through-penetrating (hyphenated) or the two-word phrase through penetrating. The unspaced, single-word spelling throughpenetrating is rarely encountered outside niche or coined terminology and may appear in product names or rapid notes rather than formal prose.

Origin and usage: The term combines the preposition through with the present participle penetrating, signaling complete traversal. In technical writing, through-penetrating is used to specify phenomena, flaws, or features that extend through an entire specimen, layer, or component. Typical contexts include materials science (through-penetrating cracks or defects), geology (through-penetrating fractures), and forensic science (through-penetrating wound descriptors in certain protocols).

Examples: A through-penetrating crack in a metal plate describes a crack that reaches both surfaces. A through-penetrating hole or bore would extend from one face to the opposite face of a part.

See also: perforation, through-going fracture, penetrating wound, permeation, through-hole. References: No widely recognized dictionary entry; usage appears in limited technical literature. Further research in domain-specific glossaries may provide instances of the term.
