Etymology: This is a plain compound: "out" (from Old English "ūt", ultimately sharing a root with the Proto-Indo-European "*úd", meaning "up" or "out") joined to "thrust", giving "outthrust" as a verb meaning to push or project outward. Its present participle, "outthrusting", takes the same sense of something pushing or jutting forth, often with force or effort. The second element, "thrust", is much older in English and comes from Old Norse "þrýsta", meaning "to press or push", which has Germanic roots. Attaching "out" simply makes the outward direction explicit, as in older compounds like "outreach" or "outstretch". The form is transparent: each part keeps its everyday meaning, so the word needs little more explanation than that.
