Note 615 — Chapter VI · ‘Nicknames.’ (continued 2)
Reading edition
‘Apple-john’ must be looked upon as a nickname taken from the fruit of that name. An apple-john was a species of apple which was never fully ripe till late in the season, when it was shrivelled. Hence Shakespeare’s allusion in 2 Henry IV. ii. 4. ‘Sweet-apple’ will belong to this category.
