Transferred or figurative sense of "apt to dissolve or melt away" is by 1837. Related: Deliquescence.
Narrowed sense of "fermented or distilled drink" (especially wine) first recorded c. 1300; the broader sense seems to have been obsolete from c. 1700. As long as liquor is in him was a Middle English expression, "as long as he is alive," that is, "as long as he has a drop of blood left." The form in Modern English has been assimilated to Latin, but the old pronunciation persists.
