+
+ ==Pronunciation==
+ * /ˈkœnən/, [ˈkœnən]^(Wiktionary)
+ * Germany: [ˈkœnn̩]^(Wiktionary)
+ * Austria, Southern-Germany, Switzerland: /ˈkœnɛn/^(Wiktionary)
+
+ ==Forms==
+ '''können''' (preterite-present, third-person singular present kann, past tense konnte, past participle gekonnt or (as an auxiliary verb) können, past subjunctive könnte, auxiliary haben)^(Wiktionary)
+ The past tense was ''kunde'', ''kunte'' (shortened ''kunt'') until the 17th century;^(Paul 2002) Goethe and Heine still use ''kunt'' in rhyme.^(Paul 2002)
+
+ ==Etymology==
+ It is [[inh|gmh|kunnen]] or [[m|gmh|künnen]], [[inh|goh|kunnan]], [[inh|gmw-pro|*kunnan]], [[inh|gem-pro|*kunnaną|t=to know, be able]].^(Kluge 2011|524)^(Pfeifer 1993)^(Wiktionary) It is a preterite-present verb: the present [[m|gem-pro|*kann]] was originally a perfect, which is why the German present is shaped like the past tense of a strong verb such as [[beginnen]].^(Kluge 2011|524)^(Pfeifer 1993)^(DWB|11, 1719) The same verb is [[got|𐌺𐌿𐌽𐌽𐌰𐌽|tr=kunnan]] (“to know”), [[non|kunna]], [[ang|cunnan]], [[ofs|kunna]] and [[osx|kunnan]], and it survives in [[nl|kunnen]], [[en|can]] and [[sv|kunna]].^(Kluge 2011|524)^(Pfeifer 1993)^(Orel 2003) Besides “to know” it meant “to be able” in all of them.^(Kluge 2011|524)
+
+ It belongs to the root [[ine-pro|*ǵneh₃-|t=to know]], found in [[grc|γιγνώσκω|tr=gignṓskō|t=I recognise]], [[la|nōscō|t=to get to know]], [[lt|žinoti|alt=žinóti|t=to know]] and [[ru|знать|tr=znatʹ|t=to know]].^(Kluge 2011|524)^(Pfeifer 1993)^(Orel 2003) The double ⟨nn⟩ and the full grade of the first syllable are unexpected: one explanation is a nasal present, which is awkward because the Germanic form continues a perfect;^(Kluge 2011|524)^(Pfeifer 1993) Seebold derives the ⟨nn⟩ from an assimilated /nə/.^(Kluge 2011|524)^(Pfeifer 1993)
+
+ The umlaut of the infinitive and the present plural first appears in Middle High German, as in the other modal verbs [[mögen]], [[müssen]] and [[dürfen]];^(Wiktionary) Wiktionary interprets it as a marker of plurality like the umlaut of noun plurals.^(Wiktionary)
+
+ ==Earliest recorded meaning==
+ Old High German ''kunnan'' is recorded from the 8th century in glosses, then in the ''Carmen ad Deum'', the Merseburg Charms, Otfrid and Notker.^(EWA|5, 888)^(Schützeichel 2012|186) It meant “to know, be acquainted with, understand, master”, and also “to be able, have the possibility”.^(EWA|5, 888)^(Schützeichel 2012|186) The original sense was mental: “to know, understand”.^(Pfeifer 1993)^(Duden 7 2020)
+
+ ==Semantic evolution==
+ Already in Middle High German the verb was used mainly of knowledge applied to an activity, a learned skill, and so moved towards “to be able”; it took over the function of Middle High German [[m|gmh|mügen]].^(Paul 2002)^(Pfeifer 1993) The old sense of knowing survives in ''auswendig können'' “to know by heart” and in ''eine Sprache können'' “to know a language”.^(Paul 2002) The use with an infinitive (''lesen können'') became usual only gradually in Old High German.^(Paul 2002) When it expresses that no one else's will stands in the way (''das kannst du meinetwegen tun''), it comes close to [[dürfen]].^(Paul 2002)
+
+ The old meaning lives on in the related words [[kennen]] (“to let know”), [[kühn]] (originally “knowing, wise”), [[kund]] (“known”) and [[Kunst]] (originally “knowledge”).^(Duden 7 2020)^(Pfeifer 1993) The infinitive used as a noun, ''das Können'' “skill, ability”, is quoted by the Grimms from Logau, Lessing and Goethe.^(DWB|11, 1741) The agent noun [[Könner]] “expert” dates from the 17th century, its feminine ''Könnerin'' from the first half of the 20th.^(Pfeifer 1993)^(Duden 7 2020)
+
+ ==Timeline==
+ * 8th century – Old High German ''kunnan'' is recorded in glosses.^(EWA|5, 888)
+ * Middle High German period – Used chiefly of learned skills; the umlauted ''künnen'' appears.^(Paul 2002)^(Wiktionary)
+ * 17th century – ''Könner'' is formed; the old past tense ''kunde'' gives way to ''konnte''.^(Pfeifer 1993)^(Paul 2002)
+ * First half of the 20th century – ''Könnerin'' appears.^(Duden 7 2020)
