Anwesenheit (presence) — In his gloss of Parmenides' "It is" in SS 1922, Heidegger comes within a hair's breadth of equating the Greek sense of being as οὐσία with "constant presence" ... but he does not. He likewise fails to do so in WS 1923-24 in his discussion of that dominating presence (παρουσία) of the Greek world, the sky. It is probably not until early 1924, in a talk that he was preparing on Nicomachean Ethics 6, that Heidegger first overtly identifies οὐσία as Anwesen (property, real estate) with constant presence. This central character first receives its full elaboration in the Aristotle course of SS 1924 under the heading of Gegenwärtigkeit, presentness. But already in November 1924, Heidegger is pondering the implication involved in the two distinctly different senses of"present" (Gegenwart), as presence (Anwesenheit) at a place or in a context (die Prasenz), and as the temporal dimension of the "now" (das Praesens). Nevertheless, in SS 1925, terms like Gegenwärtigkeit, Anwesenheit, and Präsenz tend to be used synonymously, even though "appresentation," with its tacit "pale and inconspicuous Anwesenheit of the world" (GA 20: 256/189), tends to suggest an absent presence. But in WS 1925-26, being as presence is made possible by the empowering presentifying (Gegenwärtigen) of the present tense, understood as the discoveredness of truth, such that presence (Anwesenheit) and the present (Gegenwart) together constitute Präsenz (GA 21: 193). Such distinctions were to have been the topic of the never-published Second Half of BT, to some extent developed in SS 1927 (cf. "Präsenz" below).
apophantisches "als" (apophantic "as") — First thematized in the gloss of Aristotle's theory of speech in SS 1922, but named as such first in a similar context in WS 1923-24, as the "as" that "shows" as opposed to the "as" that distinguishes, the "critical 'as.'" Its distinction from the hermeneutic "as" occurs first in WS 1925-26.
Apprasentation, apprasentieren (appresentation, appresent) — Taken from Husserl's Ideen II, they appear only in SS 1925 to describe 1) the relations of presence between world and things, and 2) the expository interpretation of such tacit presences. Replaced primarily by Gegenwärtigen (presenting, making present, presentifying), also of Husserlian coinage, but also synonyms like mitentdecken (co-discovering). Notes in his Moser transcript of SS 1925 indicate that Heidegger first experimented with alternatives like beibringen (bringing forward) and freigeben (opening, clearing, making free), both frequently used in Sein und Zeit.
Augenblick (the moment) — First thematized in translating Aristotle's καιρός in Oct. 1922, where phronetic insight is regarded as the way in which the "full moment is held in troth" (p. 36). This translation from the Greek also plays a major role in SS 1924 in depicting rhetorical-political
