Etymology

It is inherited from Middle High German wesenlich, inherited from Old High German wesantlīh (“being, substantial”), an adjective formed with -līh beside Old High German wesan (“being, existence”), the infinitive of the verb “to be, stay” used as a noun.[2][3][4] Wiktionary describes it as a calque of Latin essentiālis (“essential”).[1] The noun survives as Wesen; the verb is Proto-Germanic *wesaną, also found in Gothic 𐍅𐌹𐍃𐌰𐌽 (wisan, “to be, remain”), Old English wesan and Old Norse vesa, and is a form of the verb sein.[3][5] It goes back to Proto-Indo-European *u̯es- (“to stay, dwell, spend the night”), which is also in Sanskrit वसति (vásati, “dwells, stays”) and in the name of the Roman goddess Latin Vesta.[3][5][6]

The ⟨t⟩ before the suffix has been explained in two ways.[2][3] Kluge sees a glide inserted from the 15th century on,[2] whereas Pfeifer and the Grimms' dictionary take it from the Old High German present participle wesant-, since it already appears in the Old High German adverb wesantlīhho (“essentially”).[3][4] In Middle High German the forms without ⟨t⟩ prevailed; the form with ⟨t⟩ became general around 1600, like eigentlich, ordentlich and namentlich.[4]

Earliest recorded meaning

Old High German wesantlīh “being, substantial” is recorded in the 9th century, and the adverb wesantlīhho “essentially” in glosses of about 1000.[3][4] In Old and Middle High German the word occurs only in religious texts, mainly those of the mystics: Meister Eckhart and Tauler wrote wesenlich, Seuse weslich.[4]

Semantic evolution

The adjective first belonged to theology and mysticism, meaning “of the essence, real, substantial”, in step with the senses of the noun Wesen “essence, substance”.[4] Middle High German also used it for “real, lasting” and “domestic”, and Early New High German for “resident, settled” and “in good condition”, senses tied to Wesen “dwelling, household”.[3] General use began only in the course of the 15th century.[4] From then on the main sense became “essential, fundamental, principal”.[4][3]

With comparatives and verbs wesentlich became an intensifier “considerably, much”, and the noun use im Wesentlichen means “on the whole” or “mainly”.[7] The form weslich lasted until the first third of the 16th century and is found once more in Harsdörffer in 1641.[4]
