Why is the ninth month called September?
1825, "dainty, mincing," from finical "too particular" (1590s), perhaps from fine (adj.) + -ical as in cynical, ironical. The -k- between the final -c- and a suffix beginning in -i, -y, or -e is an orthographic rule to mark the pronunciation of -c- as "k" (cf. picnicking, trafficking, panicky, shellacked).
