What is the meaning of the inflection 若かりき?


I encountered what I think is an inflection of the adjective 若い and I couldn't
find a suitable explanation for it.

Here is the inflection in context:

はにかみて君若かりきさかづきを挙げて銀座に相別れにき…

Any clues would be greatly appreciated.




若かりき is an archaic form of 若かった.

[き](https://dictionary.goo.ne.jp/word/%E3%81%8D/#jn-50189) is an auxiliary
verb indicating past tense. So 君若かりき is in the sentence-ending form and means
_you were young_. As explained in the Weblio entry, し is a pre-noun form of き.
Thus 若かりし is usually followed by a noun, like 若かりしとき = when (subj) was young.
