In the IE languages was there some suffix that
distinguish tree names and their respective fruits.
For example, Latin has female gender for trees and
neuter for fruits: malus "apple-tree" and malum "apple", pirus "pear-tree" and
pirum "pear". In Portuguese we have the suffix -eira/o for trees: pe^ra "pear",
pereira "pear-tree".
Is there another example for another IE languages?
Any common formation? Any sign that PIE had names for many trees and their
respective fruits?
