Part 2, 16 bytes

english::ordinal

Requires the english package (which is not installed on TIO, unfortunately).

english::ordinal(f(22)) outputs first second third fourth fifth sixth seventh eighth ninth tenth eleventh twelfth thirteenth fourteenth fifteenth sixteenth seventeenth eighteenth nineteenth twentieth twenty first twenty second.

Of course, part 1 could be made much shorter (3 bytes: seq), but that would go against the constraint that part 2 has to be no longer than part 1.
