Inoculate

It is tempting to spell the verb 'to inoculate' with a double n - or with a double '-c-'. Don't fall into these traps! (The verb is derived from the Latin roots in-, meaning 'into', and oculus ('an eye'), which starts with the vowel 'o-', not with 'n-'. Therefore the full word only has one '-n-'.)

Spelling confusion may be caused by vaccinate, vaccine etc, words which have, in general use, very similar meanings - but written with two '-c-'s. (They are derived from Latin vacca, 'cow'.)


Etymological note: inoculate is derived from the Latin noun oculus, a diminutive of 'eye', with the suffix -cule. It developed figurative meanings early on:
  • in classical Latin, it was used for a 'bud' in a plant, which resembles an eye peeping out of the main growth;
  • in the Renaissance, it was used for round openings in architecture, particularly those windows also called oeil-de-boeuf (French for 'bull's eye');
  • in archaeology, an oculus is a name given to a motif of two linked circles or spirals;
  • and in more recent decorative art, the oculus is one name given to the central knob of a spiral, whether in carving (as in decorative capitals of columns) or calligraphy.
